Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546644, here are decompositions:

7 + 31546637 = 31546644
11 + 31546633 = 31546644
23 + 31546621 = 31546644
43 + 31546601 = 31546644
47 + 31546597 = 31546644
53 + 31546591 = 31546644
61 + 31546583 = 31546644
71 + 31546573 = 31546644

Showing the first eight; more decompositions exist.
