Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526208, here are decompositions:

  • 11 + 31526197 = 31526208
  • 17 + 31526191 = 31526208
  • 19 + 31526189 = 31526208
  • 67 + 31526141 = 31526208
  • 139 + 31526069 = 31526208
  • 151 + 31526057 = 31526208
  • 157 + 31526051 = 31526208
  • 227 + 31525981 = 31526208

Showing the first eight; more decompositions exist.
