Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541496, here are decompositions:

  • 13 + 31541483 = 31541496
  • 29 + 31541467 = 31541496
  • 47 + 31541449 = 31541496
  • 59 + 31541437 = 31541496
  • 67 + 31541429 = 31541496
  • 79 + 31541417 = 31541496
  • 97 + 31541399 = 31541496
  • 137 + 31541359 = 31541496

Showing the first eight; more decompositions exist.
