Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596742, here are decompositions:

  • 29 + 31596713 = 31596742
  • 71 + 31596671 = 31596742
  • 131 + 31596611 = 31596742
  • 269 + 31596473 = 31596742
  • 431 + 31596311 = 31596742
  • 449 + 31596293 = 31596742
  • 599 + 31596143 = 31596742
  • 701 + 31596041 = 31596742

Showing the first eight; more decompositions exist.
