Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526178, here are decompositions:

  • 37 + 31526141 = 31526178
  • 109 + 31526069 = 31526178
  • 127 + 31526051 = 31526178
  • 157 + 31526021 = 31526178
  • 197 + 31525981 = 31526178
  • 227 + 31525951 = 31526178
  • 251 + 31525927 = 31526178
  • 269 + 31525909 = 31526178

Showing the first eight; more decompositions exist.
