Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997240, here are decompositions:

  • 89 + 997151 = 997240
  • 131 + 997109 = 997240
  • 137 + 997103 = 997240
  • 149 + 997091 = 997240
  • 197 + 997043 = 997240
  • 227 + 997013 = 997240
  • 239 + 997001 = 997240
  • 353 + 996887 = 997240

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 997,240 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 997240 first appears in π at position 258,948 of the decimal expansion (the 258,948ordinal-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.
