Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626426, here are decompositions:

  • 5 + 31626421 = 31626426
  • 19 + 31626407 = 31626426
  • 37 + 31626389 = 31626426
  • 43 + 31626383 = 31626426
  • 59 + 31626367 = 31626426
  • 67 + 31626359 = 31626426
  • 89 + 31626337 = 31626426
  • 103 + 31626323 = 31626426

Showing the first eight; more decompositions exist.
