Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527974, here are decompositions:

  • 7 + 31527967 = 31527974
  • 43 + 31527931 = 31527974
  • 61 + 31527913 = 31527974
  • 157 + 31527817 = 31527974
  • 193 + 31527781 = 31527974
  • 271 + 31527703 = 31527974
  • 277 + 31527697 = 31527974
  • 397 + 31527577 = 31527974

Showing the first eight; more decompositions exist.
