Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445704, here are decompositions:

  • 11 + 31445693 = 31445704
  • 23 + 31445681 = 31445704
  • 41 + 31445663 = 31445704
  • 53 + 31445651 = 31445704
  • 83 + 31445621 = 31445704
  • 131 + 31445573 = 31445704
  • 197 + 31445507 = 31445704
  • 317 + 31445387 = 31445704

Showing the first eight; more decompositions exist.
