Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478650, here are decompositions:

  • 13 + 478637 = 478650
  • 19 + 478631 = 478650
  • 23 + 478627 = 478650
  • 47 + 478603 = 478650
  • 61 + 478589 = 478650
  • 71 + 478579 = 478650
  • 79 + 478571 = 478650
  • 127 + 478523 = 478650

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 478,650 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 478650 first appears in π at position 206,639 of the decimal expansion (the 206,639ordinal-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.
