Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526310, here are decompositions:

  • 29 + 31526281 = 31526310
  • 37 + 31526273 = 31526310
  • 71 + 31526239 = 31526310
  • 83 + 31526227 = 31526310
  • 89 + 31526221 = 31526310
  • 97 + 31526213 = 31526310
  • 103 + 31526207 = 31526310
  • 113 + 31526197 = 31526310

Showing the first eight; more decompositions exist.
