Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560444, here are decompositions:

7 + 31560437 = 31560444
11 + 31560433 = 31560444
37 + 31560407 = 31560444
43 + 31560401 = 31560444
53 + 31560391 = 31560444
61 + 31560383 = 31560444
101 + 31560343 = 31560444
103 + 31560341 = 31560444

Showing the first eight; more decompositions exist.
