Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556504, here are decompositions:

3 + 31556501 = 31556504
37 + 31556467 = 31556504
43 + 31556461 = 31556504
97 + 31556407 = 31556504
151 + 31556353 = 31556504
163 + 31556341 = 31556504
181 + 31556323 = 31556504
211 + 31556293 = 31556504

Showing the first eight; more decompositions exist.
