Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540878, here are decompositions:

  • 7 + 540871 = 540878
  • 97 + 540781 = 540878
  • 109 + 540769 = 540878
  • 127 + 540751 = 540878
  • 181 + 540697 = 540878
  • 199 + 540679 = 540878
  • 337 + 540541 = 540878
  • 367 + 540511 = 540878

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 540,878 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 540878 first appears in π at position 816,246 of the decimal expansion (the 816,246ordinal-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.
