Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528118, here are decompositions:

  • 7 + 31528111 = 31528118
  • 151 + 31527967 = 31528118
  • 331 + 31527787 = 31528118
  • 337 + 31527781 = 31528118
  • 409 + 31527709 = 31528118
  • 421 + 31527697 = 31528118
  • 541 + 31527577 = 31528118
  • 577 + 31527541 = 31528118

Showing the first eight; more decompositions exist.
