Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542674, here are decompositions:

  • 43 + 31542631 = 31542674
  • 61 + 31542613 = 31542674
  • 127 + 31542547 = 31542674
  • 151 + 31542523 = 31542674
  • 277 + 31542397 = 31542674
  • 283 + 31542391 = 31542674
  • 571 + 31542103 = 31542674
  • 607 + 31542067 = 31542674

Showing the first eight; more decompositions exist.
