Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8258, here are decompositions:

  • 37 + 8221 = 8258
  • 67 + 8191 = 8258
  • 79 + 8179 = 8258
  • 97 + 8161 = 8258
  • 157 + 8101 = 8258
  • 199 + 8059 = 8258
  • 241 + 8017 = 8258
  • 307 + 7951 = 8258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8258 first appears in π at position 2,032 of the decimal expansion (the 2,032ordinal-suffix:nd 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.
