Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526160, here are decompositions:

  • 19 + 31526141 = 31526160
  • 73 + 31526087 = 31526160
  • 97 + 31526063 = 31526160
  • 103 + 31526057 = 31526160
  • 109 + 31526051 = 31526160
  • 139 + 31526021 = 31526160
  • 179 + 31525981 = 31526160
  • 233 + 31525927 = 31526160

Showing the first eight; more decompositions exist.
