Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552936, here are decompositions:

17 + 31552919 = 31552936
29 + 31552907 = 31552936
53 + 31552883 = 31552936
83 + 31552853 = 31552936
89 + 31552847 = 31552936
227 + 31552709 = 31552936
293 + 31552643 = 31552936
347 + 31552589 = 31552936

Showing the first eight; more decompositions exist.
