Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550374, here are decompositions:

3 + 31550371 = 31550374
17 + 31550357 = 31550374
47 + 31550327 = 31550374
173 + 31550201 = 31550374
197 + 31550177 = 31550374
263 + 31550111 = 31550374
281 + 31550093 = 31550374
311 + 31550063 = 31550374

Showing the first eight; more decompositions exist.
