Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550292, here are decompositions:

5 + 31550287 = 31550292
41 + 31550251 = 31550292
71 + 31550221 = 31550292
79 + 31550213 = 31550292
113 + 31550179 = 31550292
139 + 31550153 = 31550292
173 + 31550119 = 31550292
181 + 31550111 = 31550292

Showing the first eight; more decompositions exist.
