Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997290, here are decompositions:

  • 11 + 997279 = 997290
  • 17 + 997273 = 997290
  • 23 + 997267 = 997290
  • 31 + 997259 = 997290
  • 43 + 997247 = 997290
  • 71 + 997219 = 997290
  • 83 + 997207 = 997290
  • 89 + 997201 = 997290

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 997,290 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 997290 first appears in π at position 144,246 of the decimal expansion (the 144,246ordinal-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.
