Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542218, here are decompositions:

  • 11 + 542207 = 542218
  • 29 + 542189 = 542218
  • 101 + 542117 = 542218
  • 107 + 542111 = 542218
  • 137 + 542081 = 542218
  • 191 + 542027 = 542218
  • 197 + 542021 = 542218
  • 227 + 541991 = 542218

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 542,218 and was likely granted around 1895.

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

Position in π

The digit sequence 542218 first appears in π at position 122,199 of the decimal expansion (the 122,199ordinal-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.
