Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518476, here are decompositions:

19 + 31518457 = 31518476
97 + 31518379 = 31518476
163 + 31518313 = 31518476
313 + 31518163 = 31518476
337 + 31518139 = 31518476
439 + 31518037 = 31518476
523 + 31517953 = 31518476
727 + 31517749 = 31518476

Showing the first eight; more decompositions exist.
