Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471632, here are decompositions:

  • 11 + 31471621 = 31471632
  • 41 + 31471591 = 31471632
  • 53 + 31471579 = 31471632
  • 83 + 31471549 = 31471632
  • 109 + 31471523 = 31471632
  • 151 + 31471481 = 31471632
  • 163 + 31471469 = 31471632
  • 193 + 31471439 = 31471632

Showing the first eight; more decompositions exist.
