Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626244, here are decompositions:

  • 11 + 31626233 = 31626244
  • 47 + 31626197 = 31626244
  • 53 + 31626191 = 31626244
  • 113 + 31626131 = 31626244
  • 191 + 31626053 = 31626244
  • 233 + 31626011 = 31626244
  • 257 + 31625987 = 31626244
  • 263 + 31625981 = 31626244

Showing the first eight; more decompositions exist.
