Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526544, here are decompositions:

  • 11 + 31526533 = 31526544
  • 17 + 31526527 = 31526544
  • 41 + 31526503 = 31526544
  • 47 + 31526497 = 31526544
  • 67 + 31526477 = 31526544
  • 113 + 31526431 = 31526544
  • 157 + 31526387 = 31526544
  • 173 + 31526371 = 31526544

Showing the first eight; more decompositions exist.
