Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997658, here are decompositions:

  • 7 + 997651 = 997658
  • 31 + 997627 = 997658
  • 61 + 997597 = 997658
  • 331 + 997327 = 997658
  • 349 + 997309 = 997658
  • 379 + 997279 = 997658
  • 439 + 997219 = 997658
  • 457 + 997201 = 997658

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 997,658 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 997658 first appears in π at position 699,128 of the decimal expansion (the 699,128ordinal-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.
