Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552926, here are decompositions:

7 + 31552919 = 31552926
19 + 31552907 = 31552926
43 + 31552883 = 31552926
47 + 31552879 = 31552926
73 + 31552853 = 31552926
79 + 31552847 = 31552926
109 + 31552817 = 31552926
179 + 31552747 = 31552926

Showing the first eight; more decompositions exist.
