Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518596, here are decompositions:

  • 3 + 31518593 = 31518596
  • 7 + 31518589 = 31518596
  • 73 + 31518523 = 31518596
  • 139 + 31518457 = 31518596
  • 283 + 31518313 = 31518596
  • 337 + 31518259 = 31518596
  • 367 + 31518229 = 31518596
  • 433 + 31518163 = 31518596

Showing the first eight; more decompositions exist.
