Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183970, here are decompositions:

  • 11 + 183959 = 183970
  • 53 + 183917 = 183970
  • 89 + 183881 = 183970
  • 173 + 183797 = 183970
  • 257 + 183713 = 183970
  • 263 + 183707 = 183970
  • 359 + 183611 = 183970
  • 383 + 183587 = 183970

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 183,970 and was likely granted around 1875.

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

Position in π

The digit sequence 183970 first appears in π at position 292,006 of the decimal expansion (the 292,006ordinal-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.
