Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508218, here are decompositions:

  • 5 + 508213 = 508218
  • 31 + 508187 = 508218
  • 47 + 508171 = 508218
  • 59 + 508159 = 508218
  • 89 + 508129 = 508218
  • 127 + 508091 = 508218
  • 131 + 508087 = 508218
  • 181 + 508037 = 508218

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 508,218 and was likely granted around 1893.

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

Position in π

The digit sequence 508218 first appears in π at position 89,396 of the decimal expansion (the 89,396ordinal-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.
