Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626704, here are decompositions:

  • 13 + 31626691 = 31626704
  • 37 + 31626667 = 31626704
  • 97 + 31626607 = 31626704
  • 157 + 31626547 = 31626704
  • 211 + 31626493 = 31626704
  • 223 + 31626481 = 31626704
  • 283 + 31626421 = 31626704
  • 337 + 31626367 = 31626704

Showing the first eight; more decompositions exist.
