Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534198, here are decompositions:

11 + 31534187 = 31534198
29 + 31534169 = 31534198
131 + 31534067 = 31534198
239 + 31533959 = 31534198
359 + 31533839 = 31534198
491 + 31533707 = 31534198
557 + 31533641 = 31534198
587 + 31533611 = 31534198

Showing the first eight; more decompositions exist.
