Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546650, here are decompositions:

13 + 31546637 = 31546650
17 + 31546633 = 31546650
29 + 31546621 = 31546650
53 + 31546597 = 31546650
59 + 31546591 = 31546650
67 + 31546583 = 31546650
97 + 31546553 = 31546650
167 + 31546483 = 31546650

Showing the first eight; more decompositions exist.
