Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552948, here are decompositions:

5 + 31552943 = 31552948
29 + 31552919 = 31552948
41 + 31552907 = 31552948
101 + 31552847 = 31552948
131 + 31552817 = 31552948
227 + 31552721 = 31552948
239 + 31552709 = 31552948
359 + 31552589 = 31552948

Showing the first eight; more decompositions exist.
