Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557446, here are decompositions:

3 + 31557443 = 31557446
13 + 31557433 = 31557446
79 + 31557367 = 31557446
103 + 31557343 = 31557446
163 + 31557283 = 31557446
199 + 31557247 = 31557446
229 + 31557217 = 31557446
307 + 31557139 = 31557446

Showing the first eight; more decompositions exist.
