Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526470, here are decompositions:

  • 47 + 31526423 = 31526470
  • 83 + 31526387 = 31526470
  • 197 + 31526273 = 31526470
  • 257 + 31526213 = 31526470
  • 263 + 31526207 = 31526470
  • 281 + 31526189 = 31526470
  • 383 + 31526087 = 31526470
  • 401 + 31526069 = 31526470

Showing the first eight; more decompositions exist.
