Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472218, here are decompositions:

  • 29 + 472189 = 472218
  • 59 + 472159 = 472218
  • 67 + 472151 = 472218
  • 79 + 472139 = 472218
  • 107 + 472111 = 472218
  • 151 + 472067 = 472218
  • 167 + 472051 = 472218
  • 191 + 472027 = 472218

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 472,218 and was likely granted around 1891.

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

Position in π

The digit sequence 472218 first appears in π at position 834,745 of the decimal expansion (the 834,745ordinal-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.
