Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493544, here are decompositions:

  • 11 + 31493533 = 31493544
  • 23 + 31493521 = 31493544
  • 31 + 31493513 = 31493544
  • 67 + 31493477 = 31493544
  • 97 + 31493447 = 31493544
  • 101 + 31493443 = 31493544
  • 167 + 31493377 = 31493544
  • 191 + 31493353 = 31493544

Showing the first eight; more decompositions exist.
