Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545826, here are decompositions:

  • 83 + 31545743 = 31545826
  • 89 + 31545737 = 31545826
  • 113 + 31545713 = 31545826
  • 197 + 31545629 = 31545826
  • 227 + 31545599 = 31545826
  • 419 + 31545407 = 31545826
  • 503 + 31545323 = 31545826
  • 509 + 31545317 = 31545826

Showing the first eight; more decompositions exist.
