Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497526, here are decompositions:

  • 3 + 31497523 = 31497526
  • 59 + 31497467 = 31497526
  • 83 + 31497443 = 31497526
  • 167 + 31497359 = 31497526
  • 173 + 31497353 = 31497526
  • 227 + 31497299 = 31497526
  • 233 + 31497293 = 31497526
  • 239 + 31497287 = 31497526

Showing the first eight; more decompositions exist.
