Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494776, here are decompositions:

  • 7 + 31494769 = 31494776
  • 13 + 31494763 = 31494776
  • 97 + 31494679 = 31494776
  • 139 + 31494637 = 31494776
  • 193 + 31494583 = 31494776
  • 223 + 31494553 = 31494776
  • 307 + 31494469 = 31494776
  • 337 + 31494439 = 31494776

Showing the first eight; more decompositions exist.
