Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488820, here are decompositions:

  • 23 + 488797 = 488820
  • 29 + 488791 = 488820
  • 41 + 488779 = 488820
  • 61 + 488759 = 488820
  • 71 + 488749 = 488820
  • 97 + 488723 = 488820
  • 103 + 488717 = 488820
  • 109 + 488711 = 488820

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 488,820 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 488820 first appears in π at position 832,412 of the decimal expansion (the 832,412ordinal-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.
