Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615646, here are decompositions:

  • 23 + 8615623 = 8615646
  • 59 + 8615587 = 8615646
  • 79 + 8615567 = 8615646
  • 103 + 8615543 = 8615646
  • 107 + 8615539 = 8615646
  • 139 + 8615507 = 8615646
  • 167 + 8615479 = 8615646
  • 173 + 8615473 = 8615646

Showing the first eight; more decompositions exist.
