Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78260, here are decompositions:

  • 19 + 78241 = 78260
  • 31 + 78229 = 78260
  • 67 + 78193 = 78260
  • 97 + 78163 = 78260
  • 103 + 78157 = 78260
  • 139 + 78121 = 78260
  • 181 + 78079 = 78260
  • 211 + 78049 = 78260

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78260 first appears in π at position 29,980 of the decimal expansion (the 29,980ordinal-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.
