Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516504, here are decompositions:

3 + 31516501 = 31516504
11 + 31516493 = 31516504
251 + 31516253 = 31516504
263 + 31516241 = 31516504
347 + 31516157 = 31516504
401 + 31516103 = 31516504
443 + 31516061 = 31516504
563 + 31515941 = 31516504

Showing the first eight; more decompositions exist.
