Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617650, here are decompositions:

  • 19 + 31617631 = 31617650
  • 67 + 31617583 = 31617650
  • 157 + 31617493 = 31617650
  • 193 + 31617457 = 31617650
  • 241 + 31617409 = 31617650
  • 271 + 31617379 = 31617650
  • 277 + 31617373 = 31617650
  • 367 + 31617283 = 31617650

Showing the first eight; more decompositions exist.
