Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478100, here are decompositions:

  • 13 + 478087 = 478100
  • 31 + 478069 = 478100
  • 37 + 478063 = 478100
  • 61 + 478039 = 478100
  • 109 + 477991 = 478100
  • 127 + 477973 = 478100
  • 277 + 477823 = 478100
  • 331 + 477769 = 478100

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 478,100 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 478100 first appears in π at position 454,945 of the decimal expansion (the 454,945ordinal-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.
