Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526190, here are decompositions:

  • 103 + 31526087 = 31526190
  • 107 + 31526083 = 31526190
  • 127 + 31526063 = 31526190
  • 139 + 31526051 = 31526190
  • 233 + 31525957 = 31526190
  • 239 + 31525951 = 31526190
  • 263 + 31525927 = 31526190
  • 271 + 31525919 = 31526190

Showing the first eight; more decompositions exist.
