Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552198, here are decompositions:

5 + 31552193 = 31552198
59 + 31552139 = 31552198
71 + 31552127 = 31552198
149 + 31552049 = 31552198
179 + 31552019 = 31552198
239 + 31551959 = 31552198
257 + 31551941 = 31552198
569 + 31551629 = 31552198

Showing the first eight; more decompositions exist.
