Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990790, here are decompositions:

  • 23 + 990767 = 990790
  • 29 + 990761 = 990790
  • 71 + 990719 = 990790
  • 83 + 990707 = 990790
  • 191 + 990599 = 990790
  • 197 + 990593 = 990790
  • 293 + 990497 = 990790
  • 401 + 990389 = 990790

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 990,790 and was likely granted around 1911.

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

Position in π

The digit sequence 990790 first appears in π at position 65,885 of the decimal expansion (the 65,885ordinal-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.
