Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997784, here are decompositions:

  • 43 + 997741 = 997784
  • 103 + 997681 = 997784
  • 157 + 997627 = 997784
  • 211 + 997573 = 997784
  • 331 + 997453 = 997784
  • 457 + 997327 = 997784
  • 577 + 997207 = 997784
  • 631 + 997153 = 997784

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 997,784 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 997784 first appears in π at position 899,689 of the decimal expansion (the 899,689ordinal-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.
