Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557134, here are decompositions:

3 + 31557131 = 31557134
13 + 31557121 = 31557134
127 + 31557007 = 31557134
211 + 31556923 = 31557134
223 + 31556911 = 31557134
277 + 31556857 = 31557134
307 + 31556827 = 31557134
331 + 31556803 = 31557134

Showing the first eight; more decompositions exist.
