Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535496, here are decompositions:

  • 29 + 31535467 = 31535496
  • 67 + 31535429 = 31535496
  • 73 + 31535423 = 31535496
  • 79 + 31535417 = 31535496
  • 233 + 31535263 = 31535496
  • 263 + 31535233 = 31535496
  • 269 + 31535227 = 31535496
  • 277 + 31535219 = 31535496

Showing the first eight; more decompositions exist.
