Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627882, here are decompositions:

  • 3 + 31627879 = 31627882
  • 71 + 31627811 = 31627882
  • 89 + 31627793 = 31627882
  • 131 + 31627751 = 31627882
  • 233 + 31627649 = 31627882
  • 281 + 31627601 = 31627882
  • 491 + 31627391 = 31627882
  • 509 + 31627373 = 31627882

Showing the first eight; more decompositions exist.
