Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535286, here are decompositions:

  • 23 + 31535263 = 31535286
  • 53 + 31535233 = 31535286
  • 59 + 31535227 = 31535286
  • 67 + 31535219 = 31535286
  • 73 + 31535213 = 31535286
  • 103 + 31535183 = 31535286
  • 113 + 31535173 = 31535286
  • 163 + 31535123 = 31535286

Showing the first eight; more decompositions exist.
