Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626760, here are decompositions:

  • 71 + 31626689 = 31626760
  • 197 + 31626563 = 31626760
  • 227 + 31626533 = 31626760
  • 353 + 31626407 = 31626760
  • 383 + 31626377 = 31626760
  • 401 + 31626359 = 31626760
  • 563 + 31626197 = 31626760
  • 569 + 31626191 = 31626760

Showing the first eight; more decompositions exist.
