Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526370, here are decompositions:

  • 11 + 31526359 = 31526370
  • 19 + 31526351 = 31526370
  • 53 + 31526317 = 31526370
  • 89 + 31526281 = 31526370
  • 97 + 31526273 = 31526370
  • 131 + 31526239 = 31526370
  • 149 + 31526221 = 31526370
  • 157 + 31526213 = 31526370

Showing the first eight; more decompositions exist.
