Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626262, here are decompositions:

  • 29 + 31626233 = 31626262
  • 53 + 31626209 = 31626262
  • 71 + 31626191 = 31626262
  • 131 + 31626131 = 31626262
  • 251 + 31626011 = 31626262
  • 281 + 31625981 = 31626262
  • 293 + 31625969 = 31626262
  • 419 + 31625843 = 31626262

Showing the first eight; more decompositions exist.
