Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550274, here are decompositions:

17 + 31550257 = 31550274
23 + 31550251 = 31550274
53 + 31550221 = 31550274
61 + 31550213 = 31550274
73 + 31550201 = 31550274
97 + 31550177 = 31550274
137 + 31550137 = 31550274
163 + 31550111 = 31550274

Showing the first eight; more decompositions exist.
