Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526318, here are decompositions:

  • 37 + 31526281 = 31526318
  • 79 + 31526239 = 31526318
  • 97 + 31526221 = 31526318
  • 127 + 31526191 = 31526318
  • 337 + 31525981 = 31526318
  • 367 + 31525951 = 31526318
  • 409 + 31525909 = 31526318
  • 541 + 31525777 = 31526318

Showing the first eight; more decompositions exist.
