Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526228, here are decompositions:

  • 7 + 31526221 = 31526228
  • 31 + 31526197 = 31526228
  • 37 + 31526191 = 31526228
  • 271 + 31525957 = 31526228
  • 277 + 31525951 = 31526228
  • 337 + 31525891 = 31526228
  • 379 + 31525849 = 31526228
  • 457 + 31525771 = 31526228

Showing the first eight; more decompositions exist.
