Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583206, here are decompositions:

  • 47 + 31583159 = 31583206
  • 59 + 31583147 = 31583206
  • 173 + 31583033 = 31583206
  • 257 + 31582949 = 31583206
  • 269 + 31582937 = 31583206
  • 293 + 31582913 = 31583206
  • 359 + 31582847 = 31583206
  • 383 + 31582823 = 31583206

Showing the first eight; more decompositions exist.
