Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612802, here are decompositions:

  • 43 + 31612759 = 31612802
  • 73 + 31612729 = 31612802
  • 139 + 31612663 = 31612802
  • 181 + 31612621 = 31612802
  • 229 + 31612573 = 31612802
  • 271 + 31612531 = 31612802
  • 349 + 31612453 = 31612802
  • 373 + 31612429 = 31612802

Showing the first eight; more decompositions exist.
