Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11258, here are decompositions:

  • 7 + 11251 = 11258
  • 19 + 11239 = 11258
  • 61 + 11197 = 11258
  • 97 + 11161 = 11258
  • 109 + 11149 = 11258
  • 127 + 11131 = 11258
  • 139 + 11119 = 11258
  • 199 + 11059 = 11258

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11258 first appears in π at position 87,584 of the decimal expansion (the 87,584ordinal-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.
