Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602650, here are decompositions:

  • 3 + 31602647 = 31602650
  • 19 + 31602631 = 31602650
  • 61 + 31602589 = 31602650
  • 193 + 31602457 = 31602650
  • 199 + 31602451 = 31602650
  • 229 + 31602421 = 31602650
  • 283 + 31602367 = 31602650
  • 433 + 31602217 = 31602650

Showing the first eight; more decompositions exist.
