Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560552, here are decompositions:

11 + 31560541 = 31560552
19 + 31560533 = 31560552
29 + 31560523 = 31560552
43 + 31560509 = 31560552
53 + 31560499 = 31560552
83 + 31560469 = 31560552
151 + 31560401 = 31560552
211 + 31560341 = 31560552

Showing the first eight; more decompositions exist.
