Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492650, here are decompositions:

  • 23 + 31492627 = 31492650
  • 47 + 31492603 = 31492650
  • 53 + 31492597 = 31492650
  • 73 + 31492577 = 31492650
  • 83 + 31492567 = 31492650
  • 97 + 31492553 = 31492650
  • 109 + 31492541 = 31492650
  • 113 + 31492537 = 31492650

Showing the first eight; more decompositions exist.
