Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523026, here are decompositions:

  • 5 + 31523021 = 31523026
  • 23 + 31523003 = 31523026
  • 47 + 31522979 = 31523026
  • 89 + 31522937 = 31523026
  • 137 + 31522889 = 31523026
  • 179 + 31522847 = 31523026
  • 443 + 31522583 = 31523026
  • 503 + 31522523 = 31523026

Showing the first eight; more decompositions exist.
