Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536470, here are decompositions:

  • 67 + 31536403 = 31536470
  • 73 + 31536397 = 31536470
  • 79 + 31536391 = 31536470
  • 109 + 31536361 = 31536470
  • 157 + 31536313 = 31536470
  • 283 + 31536187 = 31536470
  • 373 + 31536097 = 31536470
  • 409 + 31536061 = 31536470

Showing the first eight; more decompositions exist.
