Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552914, here are decompositions:

7 + 31552907 = 31552914
23 + 31552891 = 31552914
31 + 31552883 = 31552914
61 + 31552853 = 31552914
67 + 31552847 = 31552914
83 + 31552831 = 31552914
97 + 31552817 = 31552914
167 + 31552747 = 31552914

Showing the first eight; more decompositions exist.
