Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552956, here are decompositions:

13 + 31552943 = 31552956
37 + 31552919 = 31552956
73 + 31552883 = 31552956
103 + 31552853 = 31552956
109 + 31552847 = 31552956
139 + 31552817 = 31552956
223 + 31552733 = 31552956
229 + 31552727 = 31552956

Showing the first eight; more decompositions exist.
