Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583302, here are decompositions:

  • 131 + 31583171 = 31583302
  • 251 + 31583051 = 31583302
  • 269 + 31583033 = 31583302
  • 353 + 31582949 = 31583302
  • 389 + 31582913 = 31583302
  • 479 + 31582823 = 31583302
  • 521 + 31582781 = 31583302
  • 563 + 31582739 = 31583302

Showing the first eight; more decompositions exist.
