Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540218, here are decompositions:

  • 31 + 540187 = 540218
  • 37 + 540181 = 540218
  • 61 + 540157 = 540218
  • 79 + 540139 = 540218
  • 97 + 540121 = 540218
  • 139 + 540079 = 540218
  • 157 + 540061 = 540218
  • 271 + 539947 = 540218

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 540,218 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 540218 first appears in π at position 90,979 of the decimal expansion (the 90,979ordinal-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.
