Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552108, here are decompositions:

59 + 31552049 = 31552108
89 + 31552019 = 31552108
131 + 31551977 = 31552108
149 + 31551959 = 31552108
167 + 31551941 = 31552108
251 + 31551857 = 31552108
281 + 31551827 = 31552108
479 + 31551629 = 31552108

Showing the first eight; more decompositions exist.
