Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617926, here are decompositions:

  • 37 + 31617889 = 31617926
  • 73 + 31617853 = 31617926
  • 163 + 31617763 = 31617926
  • 229 + 31617697 = 31617926
  • 367 + 31617559 = 31617926
  • 397 + 31617529 = 31617926
  • 433 + 31617493 = 31617926
  • 523 + 31617403 = 31617926

Showing the first eight; more decompositions exist.
