Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28276, here are decompositions:

  • 47 + 28229 = 28276
  • 113 + 28163 = 28276
  • 167 + 28109 = 28276
  • 179 + 28097 = 28276
  • 257 + 28019 = 28276
  • 293 + 27983 = 28276
  • 359 + 27917 = 28276
  • 383 + 27893 = 28276

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28276 first appears in π at position 18,855 of the decimal expansion (the 18,855ordinal-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.
