Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550476, here are decompositions:

5 + 31550471 = 31550476
17 + 31550459 = 31550476
29 + 31550447 = 31550476
137 + 31550339 = 31550476
149 + 31550327 = 31550476
263 + 31550213 = 31550476
383 + 31550093 = 31550476
449 + 31550027 = 31550476

Showing the first eight; more decompositions exist.
