Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526284, here are decompositions:

  • 3 + 31526281 = 31526284
  • 11 + 31526273 = 31526284
  • 71 + 31526213 = 31526284
  • 197 + 31526087 = 31526284
  • 227 + 31526057 = 31526284
  • 233 + 31526051 = 31526284
  • 263 + 31526021 = 31526284
  • 443 + 31525841 = 31526284

Showing the first eight; more decompositions exist.
