Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603610, here are decompositions:

  • 43 + 31603567 = 31603610
  • 229 + 31603381 = 31603610
  • 349 + 31603261 = 31603610
  • 463 + 31603147 = 31603610
  • 487 + 31603123 = 31603610
  • 499 + 31603111 = 31603610
  • 601 + 31603009 = 31603610
  • 733 + 31602877 = 31603610

Showing the first eight; more decompositions exist.
