Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23678, here are decompositions:

  • 7 + 23671 = 23678
  • 79 + 23599 = 23678
  • 97 + 23581 = 23678
  • 139 + 23539 = 23678
  • 181 + 23497 = 23678
  • 307 + 23371 = 23678
  • 367 + 23311 = 23678
  • 409 + 23269 = 23678

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23678 first appears in π at position 101,003 of the decimal expansion (the 101,003ordinal-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.
