Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526886, here are decompositions:

  • 5 + 31526881 = 31526886
  • 7 + 31526879 = 31526886
  • 23 + 31526863 = 31526886
  • 67 + 31526819 = 31526886
  • 109 + 31526777 = 31526886
  • 113 + 31526773 = 31526886
  • 137 + 31526749 = 31526886
  • 163 + 31526723 = 31526886

Showing the first eight; more decompositions exist.
