Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593480, here are decompositions:

  • 19 + 31593461 = 31593480
  • 43 + 31593437 = 31593480
  • 89 + 31593391 = 31593480
  • 103 + 31593377 = 31593480
  • 137 + 31593343 = 31593480
  • 167 + 31593313 = 31593480
  • 173 + 31593307 = 31593480
  • 181 + 31593299 = 31593480

Showing the first eight; more decompositions exist.
