Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626412, here are decompositions:

  • 5 + 31626407 = 31626412
  • 23 + 31626389 = 31626412
  • 29 + 31626383 = 31626412
  • 53 + 31626359 = 31626412
  • 89 + 31626323 = 31626412
  • 179 + 31626233 = 31626412
  • 281 + 31626131 = 31626412
  • 359 + 31626053 = 31626412

Showing the first eight; more decompositions exist.
