Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938288, here are decompositions:

  • 31 + 938257 = 938288
  • 37 + 938251 = 938288
  • 181 + 938107 = 938288
  • 199 + 938089 = 938288
  • 229 + 938059 = 938288
  • 271 + 938017 = 938288
  • 397 + 937891 = 938288
  • 487 + 937801 = 938288

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 938,288 and was likely granted around 1909.

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

Position in π

The digit sequence 938288 first appears in π at position 388,564 of the decimal expansion (the 388,564ordinal-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.
