Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488100, here are decompositions:

  • 31 + 488069 = 488100
  • 43 + 488057 = 488100
  • 79 + 488021 = 488100
  • 89 + 488011 = 488100
  • 97 + 488003 = 488100
  • 103 + 487997 = 488100
  • 127 + 487973 = 488100
  • 157 + 487943 = 488100

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 488,100 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 488100 first appears in π at position 543,517 of the decimal expansion (the 543,517ordinal-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.
