Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28316, here are decompositions:

  • 7 + 28309 = 28316
  • 19 + 28297 = 28316
  • 37 + 28279 = 28316
  • 97 + 28219 = 28316
  • 193 + 28123 = 28316
  • 229 + 28087 = 28316
  • 349 + 27967 = 28316
  • 373 + 27943 = 28316

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28316 first appears in π at position 31,053 of the decimal expansion (the 31,053ordinal-suffix:rd 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.
