Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526080, here are decompositions:

  • 11 + 31526069 = 31526080
  • 17 + 31526063 = 31526080
  • 23 + 31526057 = 31526080
  • 29 + 31526051 = 31526080
  • 59 + 31526021 = 31526080
  • 167 + 31525913 = 31526080
  • 191 + 31525889 = 31526080
  • 239 + 31525841 = 31526080

Showing the first eight; more decompositions exist.
