Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478980, here are decompositions:

  • 13 + 478967 = 478980
  • 17 + 478963 = 478980
  • 37 + 478943 = 478980
  • 43 + 478937 = 478980
  • 53 + 478927 = 478980
  • 67 + 478913 = 478980
  • 79 + 478901 = 478980
  • 83 + 478897 = 478980

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 478,980 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 478980 first appears in π at position 217,829 of the decimal expansion (the 217,829ordinal-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.
