Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977800, here are decompositions:

  • 53 + 977747 = 977800
  • 107 + 977693 = 977800
  • 191 + 977609 = 977800
  • 233 + 977567 = 977800
  • 293 + 977507 = 977800
  • 353 + 977447 = 977800
  • 389 + 977411 = 977800
  • 431 + 977369 = 977800

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 977,800 and was likely granted around 1910.

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

Position in π

The digit sequence 977800 first appears in π at position 294,987 of the decimal expansion (the 294,987ordinal-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.
