Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527744, here are decompositions:

  • 41 + 31527703 = 31527744
  • 43 + 31527701 = 31527744
  • 47 + 31527697 = 31527744
  • 67 + 31527677 = 31527744
  • 167 + 31527577 = 31527744
  • 211 + 31527533 = 31527744
  • 223 + 31527521 = 31527744
  • 263 + 31527481 = 31527744

Showing the first eight; more decompositions exist.
