Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526538, here are decompositions:

  • 5 + 31526533 = 31526538
  • 11 + 31526527 = 31526538
  • 41 + 31526497 = 31526538
  • 61 + 31526477 = 31526538
  • 107 + 31526431 = 31526538
  • 149 + 31526389 = 31526538
  • 151 + 31526387 = 31526538
  • 167 + 31526371 = 31526538

Showing the first eight; more decompositions exist.
