Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552902, here are decompositions:

11 + 31552891 = 31552902
19 + 31552883 = 31552902
23 + 31552879 = 31552902
71 + 31552831 = 31552902
181 + 31552721 = 31552902
193 + 31552709 = 31552902
263 + 31552639 = 31552902
281 + 31552621 = 31552902

Showing the first eight; more decompositions exist.
