Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583792, here are decompositions:

  • 13 + 31583779 = 31583792
  • 43 + 31583749 = 31583792
  • 151 + 31583641 = 31583792
  • 271 + 31583521 = 31583792
  • 283 + 31583509 = 31583792
  • 379 + 31583413 = 31583792
  • 439 + 31583353 = 31583792
  • 523 + 31583269 = 31583792

Showing the first eight; more decompositions exist.
