Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552910, here are decompositions:

3 + 31552907 = 31552910
19 + 31552891 = 31552910
31 + 31552879 = 31552910
79 + 31552831 = 31552910
163 + 31552747 = 31552910
229 + 31552681 = 31552910
271 + 31552639 = 31552910
307 + 31552603 = 31552910

Showing the first eight; more decompositions exist.
