Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552924, here are decompositions:

5 + 31552919 = 31552924
17 + 31552907 = 31552924
41 + 31552883 = 31552924
71 + 31552853 = 31552924
107 + 31552817 = 31552924
191 + 31552733 = 31552924
197 + 31552727 = 31552924
281 + 31552643 = 31552924

Showing the first eight; more decompositions exist.
