Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544078, here are decompositions:

  • 37 + 31544041 = 31544078
  • 67 + 31544011 = 31544078
  • 151 + 31543927 = 31544078
  • 367 + 31543711 = 31544078
  • 409 + 31543669 = 31544078
  • 499 + 31543579 = 31544078
  • 547 + 31543531 = 31544078
  • 859 + 31543219 = 31544078

Showing the first eight; more decompositions exist.
