Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508626, here are decompositions:

  • 5 + 31508621 = 31508626
  • 47 + 31508579 = 31508626
  • 59 + 31508567 = 31508626
  • 173 + 31508453 = 31508626
  • 263 + 31508363 = 31508626
  • 449 + 31508177 = 31508626
  • 467 + 31508159 = 31508626
  • 587 + 31508039 = 31508626

Showing the first eight; more decompositions exist.
