Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724790, here are decompositions:

  • 3 + 8724787 = 8724790
  • 71 + 8724719 = 8724790
  • 149 + 8724641 = 8724790
  • 293 + 8724497 = 8724790
  • 311 + 8724479 = 8724790
  • 353 + 8724437 = 8724790
  • 419 + 8724371 = 8724790
  • 443 + 8724347 = 8724790

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,724,790 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8724790 first appears in π at position 705,911 of the decimal expansion (the 705,911ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
