Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497516, here are decompositions:

  • 47 + 31497469 = 31497516
  • 53 + 31497463 = 31497516
  • 67 + 31497449 = 31497516
  • 73 + 31497443 = 31497516
  • 107 + 31497409 = 31497516
  • 157 + 31497359 = 31497516
  • 163 + 31497353 = 31497516
  • 179 + 31497337 = 31497516

Showing the first eight; more decompositions exist.
