Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525880, here are decompositions:

  • 11 + 525869 = 525880
  • 41 + 525839 = 525880
  • 71 + 525809 = 525880
  • 107 + 525773 = 525880
  • 149 + 525731 = 525880
  • 167 + 525713 = 525880
  • 239 + 525641 = 525880
  • 281 + 525599 = 525880

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 525,880 and was likely granted around 1894.

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

Position in π

The digit sequence 525880 first appears in π at position 897,205 of the decimal expansion (the 897,205ordinal-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.
