Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552962, here are decompositions:

19 + 31552943 = 31552962
43 + 31552919 = 31552962
71 + 31552891 = 31552962
79 + 31552883 = 31552962
83 + 31552879 = 31552962
109 + 31552853 = 31552962
131 + 31552831 = 31552962
229 + 31552733 = 31552962

Showing the first eight; more decompositions exist.
