Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527252, here are decompositions:

  • 5 + 31527247 = 31527252
  • 19 + 31527233 = 31527252
  • 41 + 31527211 = 31527252
  • 59 + 31527193 = 31527252
  • 61 + 31527191 = 31527252
  • 79 + 31527173 = 31527252
  • 101 + 31527151 = 31527252
  • 103 + 31527149 = 31527252

Showing the first eight; more decompositions exist.
