Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105284, here are decompositions:

  • 7 + 105277 = 105284
  • 31 + 105253 = 105284
  • 73 + 105211 = 105284
  • 313 + 104971 = 105284
  • 331 + 104953 = 105284
  • 337 + 104947 = 105284
  • 367 + 104917 = 105284
  • 373 + 104911 = 105284

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 105,284 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 105284 first appears in π at position 425,049 of the decimal expansion (the 425,049ordinal-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.
