Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68858, here are decompositions:

  • 37 + 68821 = 68858
  • 67 + 68791 = 68858
  • 109 + 68749 = 68858
  • 199 + 68659 = 68858
  • 277 + 68581 = 68858
  • 337 + 68521 = 68858
  • 367 + 68491 = 68858
  • 409 + 68449 = 68858

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 68858 first appears in π at position 120,079 of the decimal expansion (the 120,079ordinal-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.
