Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544866, here are decompositions:

  • 47 + 31544819 = 31544866
  • 83 + 31544783 = 31544866
  • 107 + 31544759 = 31544866
  • 149 + 31544717 = 31544866
  • 293 + 31544573 = 31544866
  • 449 + 31544417 = 31544866
  • 503 + 31544363 = 31544866
  • 569 + 31544297 = 31544866

Showing the first eight; more decompositions exist.
