Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544040, here are decompositions:

  • 7 + 31544033 = 31544040
  • 19 + 31544021 = 31544040
  • 29 + 31544011 = 31544040
  • 43 + 31543997 = 31544040
  • 53 + 31543987 = 31544040
  • 61 + 31543979 = 31544040
  • 79 + 31543961 = 31544040
  • 113 + 31543927 = 31544040

Showing the first eight; more decompositions exist.
