Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526162, here are decompositions:

  • 79 + 31526083 = 31526162
  • 181 + 31525981 = 31526162
  • 211 + 31525951 = 31526162
  • 271 + 31525891 = 31526162
  • 313 + 31525849 = 31526162
  • 379 + 31525783 = 31526162
  • 439 + 31525723 = 31526162
  • 463 + 31525699 = 31526162

Showing the first eight; more decompositions exist.
