Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545632, here are decompositions:

  • 3 + 31545629 = 31545632
  • 163 + 31545469 = 31545632
  • 193 + 31545439 = 31545632
  • 241 + 31545391 = 31545632
  • 421 + 31545211 = 31545632
  • 541 + 31545091 = 31545632
  • 571 + 31545061 = 31545632
  • 631 + 31545001 = 31545632

Showing the first eight; more decompositions exist.
