Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490940, here are decompositions:

  • 3 + 490937 = 490940
  • 13 + 490927 = 490940
  • 19 + 490921 = 490940
  • 103 + 490837 = 490940
  • 157 + 490783 = 490940
  • 199 + 490741 = 490940
  • 277 + 490663 = 490940
  • 313 + 490627 = 490940

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 490,940 and was likely granted around 1892.

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

Position in π

The digit sequence 490940 first appears in π at position 183,957 of the decimal expansion (the 183,957ordinal-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.
