Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542734, here are decompositions:

  • 7 + 31542727 = 31542734
  • 31 + 31542703 = 31542734
  • 37 + 31542697 = 31542734
  • 103 + 31542631 = 31542734
  • 211 + 31542523 = 31542734
  • 277 + 31542457 = 31542734
  • 337 + 31542397 = 31542734
  • 571 + 31542163 = 31542734

Showing the first eight; more decompositions exist.
