Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542776, here are decompositions:

  • 73 + 31542703 = 31542776
  • 79 + 31542697 = 31542776
  • 163 + 31542613 = 31542776
  • 229 + 31542547 = 31542776
  • 337 + 31542439 = 31542776
  • 379 + 31542397 = 31542776
  • 547 + 31542229 = 31542776
  • 613 + 31542163 = 31542776

Showing the first eight; more decompositions exist.
