Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546664, here are decompositions:

3 + 31546661 = 31546664
7 + 31546657 = 31546664
31 + 31546633 = 31546664
43 + 31546621 = 31546664
67 + 31546597 = 31546664
73 + 31546591 = 31546664
181 + 31546483 = 31546664
271 + 31546393 = 31546664

Showing the first eight; more decompositions exist.
