Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445796, here are decompositions:

  • 7 + 31445789 = 31445796
  • 73 + 31445723 = 31445796
  • 103 + 31445693 = 31445796
  • 223 + 31445573 = 31445796
  • 257 + 31445539 = 31445796
  • 307 + 31445489 = 31445796
  • 337 + 31445459 = 31445796
  • 353 + 31445443 = 31445796

Showing the first eight; more decompositions exist.
