Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496618, here are decompositions:

  • 7 + 31496611 = 31496618
  • 19 + 31496599 = 31496618
  • 31 + 31496587 = 31496618
  • 67 + 31496551 = 31496618
  • 79 + 31496539 = 31496618
  • 199 + 31496419 = 31496618
  • 229 + 31496389 = 31496618
  • 397 + 31496221 = 31496618

Showing the first eight; more decompositions exist.
