Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540490, here are decompositions:

  • 29 + 540461 = 540490
  • 53 + 540437 = 540490
  • 101 + 540389 = 540490
  • 107 + 540383 = 540490
  • 113 + 540377 = 540490
  • 239 + 540251 = 540490
  • 257 + 540233 = 540490
  • 311 + 540179 = 540490

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 540,490 and was likely granted around 1894.

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

Position in π

The digit sequence 540490 first appears in π at position 639,814 of the decimal expansion (the 639,814ordinal-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.
