Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532744, here are decompositions:

  • 7 + 31532737 = 31532744
  • 151 + 31532593 = 31532744
  • 157 + 31532587 = 31532744
  • 163 + 31532581 = 31532744
  • 193 + 31532551 = 31532744
  • 223 + 31532521 = 31532744
  • 307 + 31532437 = 31532744
  • 421 + 31532323 = 31532744

Showing the first eight; more decompositions exist.
