Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539504, here are decompositions:

  • 5 + 31539499 = 31539504
  • 37 + 31539467 = 31539504
  • 83 + 31539421 = 31539504
  • 103 + 31539401 = 31539504
  • 127 + 31539377 = 31539504
  • 137 + 31539367 = 31539504
  • 151 + 31539353 = 31539504
  • 167 + 31539337 = 31539504

Showing the first eight; more decompositions exist.
