Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526748, here are decompositions:

  • 17 + 31526731 = 31526748
  • 59 + 31526689 = 31526748
  • 79 + 31526669 = 31526748
  • 101 + 31526647 = 31526748
  • 131 + 31526617 = 31526748
  • 251 + 31526497 = 31526748
  • 271 + 31526477 = 31526748
  • 317 + 31526431 = 31526748

Showing the first eight; more decompositions exist.
