Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478660, here are decompositions:

  • 23 + 478637 = 478660
  • 29 + 478631 = 478660
  • 71 + 478589 = 478660
  • 89 + 478571 = 478660
  • 137 + 478523 = 478660
  • 167 + 478493 = 478660
  • 179 + 478481 = 478660
  • 227 + 478433 = 478660

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 478,660 and was likely granted around 1892.

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

Position in π

The digit sequence 478660 first appears in π at position 200,610 of the decimal expansion (the 200,610ordinal-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.
