Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625082, here are decompositions:

  • 23 + 31625059 = 31625082
  • 43 + 31625039 = 31625082
  • 103 + 31624979 = 31625082
  • 131 + 31624951 = 31625082
  • 233 + 31624849 = 31625082
  • 283 + 31624799 = 31625082
  • 383 + 31624699 = 31625082
  • 409 + 31624673 = 31625082

Showing the first eight; more decompositions exist.
