Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583358, here are decompositions:

  • 5 + 31583353 = 31583358
  • 7 + 31583351 = 31583358
  • 89 + 31583269 = 31583358
  • 101 + 31583257 = 31583358
  • 199 + 31583159 = 31583358
  • 211 + 31583147 = 31583358
  • 227 + 31583131 = 31583358
  • 271 + 31583087 = 31583358

Showing the first eight; more decompositions exist.
