Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78150, here are decompositions:

  • 11 + 78139 = 78150
  • 13 + 78137 = 78150
  • 29 + 78121 = 78150
  • 71 + 78079 = 78150
  • 101 + 78049 = 78150
  • 109 + 78041 = 78150
  • 151 + 77999 = 78150
  • 167 + 77983 = 78150

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78150 first appears in π at position 65,236 of the decimal expansion (the 65,236ordinal-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.
