Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546728, here are decompositions:

7 + 31546721 = 31546728
11 + 31546717 = 31546728
19 + 31546709 = 31546728
67 + 31546661 = 31546728
71 + 31546657 = 31546728
107 + 31546621 = 31546728
127 + 31546601 = 31546728
131 + 31546597 = 31546728

Showing the first eight; more decompositions exist.
