Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583252, here are decompositions:

  • 229 + 31583023 = 31583252
  • 271 + 31582981 = 31583252
  • 433 + 31582819 = 31583252
  • 523 + 31582729 = 31583252
  • 619 + 31582633 = 31583252
  • 643 + 31582609 = 31583252
  • 739 + 31582513 = 31583252
  • 853 + 31582399 = 31583252

Showing the first eight; more decompositions exist.
