Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545682, here are decompositions:

  • 41 + 31545641 = 31545682
  • 53 + 31545629 = 31545682
  • 59 + 31545623 = 31545682
  • 71 + 31545611 = 31545682
  • 83 + 31545599 = 31545682
  • 281 + 31545401 = 31545682
  • 353 + 31545329 = 31545682
  • 359 + 31545323 = 31545682

Showing the first eight; more decompositions exist.
