Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724500, here are decompositions:

  • 3 + 8724497 = 8724500
  • 7 + 8724493 = 8724500
  • 13 + 8724487 = 8724500
  • 79 + 8724421 = 8724500
  • 181 + 8724319 = 8724500
  • 199 + 8724301 = 8724500
  • 241 + 8724259 = 8724500
  • 277 + 8724223 = 8724500

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 8,724,500 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 8724500 first appears in π at position 255,400 of the decimal expansion (the 255,400ordinal-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.
