Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550494, here are decompositions:

23 + 31550471 = 31550494
47 + 31550447 = 31550494
137 + 31550357 = 31550494
167 + 31550327 = 31550494
281 + 31550213 = 31550494
293 + 31550201 = 31550494
317 + 31550177 = 31550494
383 + 31550111 = 31550494

Showing the first eight; more decompositions exist.
