Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584226, here are decompositions:

  • 29 + 31584197 = 31584226
  • 53 + 31584173 = 31584226
  • 83 + 31584143 = 31584226
  • 227 + 31583999 = 31584226
  • 389 + 31583837 = 31584226
  • 449 + 31583777 = 31584226
  • 563 + 31583663 = 31584226
  • 593 + 31583633 = 31584226

Showing the first eight; more decompositions exist.
