Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620934, here are decompositions:

  • 3 + 31620931 = 31620934
  • 113 + 31620821 = 31620934
  • 197 + 31620737 = 31620934
  • 251 + 31620683 = 31620934
  • 353 + 31620581 = 31620934
  • 461 + 31620473 = 31620934
  • 491 + 31620443 = 31620934
  • 503 + 31620431 = 31620934

Showing the first eight; more decompositions exist.
