Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525174, here are decompositions:

  • 11 + 31525163 = 31525174
  • 47 + 31525127 = 31525174
  • 53 + 31525121 = 31525174
  • 71 + 31525103 = 31525174
  • 137 + 31525037 = 31525174
  • 167 + 31525007 = 31525174
  • 281 + 31524893 = 31525174
  • 311 + 31524863 = 31525174

Showing the first eight; more decompositions exist.
