Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506218, here are decompositions:

  • 5 + 506213 = 506218
  • 17 + 506201 = 506218
  • 47 + 506171 = 506218
  • 71 + 506147 = 506218
  • 239 + 505979 = 506218
  • 257 + 505961 = 506218
  • 269 + 505949 = 506218
  • 311 + 505907 = 506218

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 506,218 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 506218 first appears in π at position 488,263 of the decimal expansion (the 488,263ordinal-suffix:rd 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.
