Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153830, here are decompositions:

  • 13 + 153817 = 153830
  • 67 + 153763 = 153830
  • 73 + 153757 = 153830
  • 97 + 153733 = 153830
  • 181 + 153649 = 153830
  • 223 + 153607 = 153830
  • 241 + 153589 = 153830
  • 307 + 153523 = 153830

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 153,830 and was likely granted around 1873.

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

Position in π

The digit sequence 153830 first appears in π at position 691,226 of the decimal expansion (the 691,226ordinal-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.
