Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150218, here are decompositions:

  • 7 + 150211 = 150218
  • 67 + 150151 = 150218
  • 127 + 150091 = 150218
  • 151 + 150067 = 150218
  • 157 + 150061 = 150218
  • 307 + 149911 = 150218
  • 379 + 149839 = 150218
  • 487 + 149731 = 150218

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 150,218 and was likely granted around 1873.

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

Position in π

The digit sequence 150218 first appears in π at position 215,132 of the decimal expansion (the 215,132ordinal-suffix:nd 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.
