Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626544, here are decompositions:

  • 11 + 31626533 = 31626544
  • 83 + 31626461 = 31626544
  • 107 + 31626437 = 31626544
  • 137 + 31626407 = 31626544
  • 167 + 31626377 = 31626544
  • 311 + 31626233 = 31626544
  • 347 + 31626197 = 31626544
  • 353 + 31626191 = 31626544

Showing the first eight; more decompositions exist.
