Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100830, here are decompositions:

  • 7 + 100823 = 100830
  • 19 + 100811 = 100830
  • 29 + 100801 = 100830
  • 31 + 100799 = 100830
  • 43 + 100787 = 100830
  • 61 + 100769 = 100830
  • 83 + 100747 = 100830
  • 89 + 100741 = 100830

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 100,830 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 100830 first appears in π at position 638,077 of the decimal expansion (the 638,077ordinal-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.
