Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101428, here are decompositions:

  • 17 + 101411 = 101428
  • 29 + 101399 = 101428
  • 149 + 101279 = 101428
  • 269 + 101159 = 101428
  • 311 + 101117 = 101428
  • 317 + 101111 = 101428
  • 347 + 101081 = 101428
  • 401 + 101027 = 101428

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 101,428 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 101428 first appears in π at position 692,084 of the decimal expansion (the 692,084ordinal-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.
