Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547852, here are decompositions:

3 + 31547849 = 31547852
13 + 31547839 = 31547852
19 + 31547833 = 31547852
103 + 31547749 = 31547852
151 + 31547701 = 31547852
181 + 31547671 = 31547852
211 + 31547641 = 31547852
223 + 31547629 = 31547852

Showing the first eight; more decompositions exist.
