Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532584, here are decompositions:

  • 3 + 31532581 = 31532584
  • 11 + 31532573 = 31532584
  • 107 + 31532477 = 31532584
  • 443 + 31532141 = 31532584
  • 467 + 31532117 = 31532584
  • 521 + 31532063 = 31532584
  • 563 + 31532021 = 31532584
  • 617 + 31531967 = 31532584

Showing the first eight; more decompositions exist.
