Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534148, here are decompositions:

7 + 31534141 = 31534148
31 + 31534117 = 31534148
97 + 31534051 = 31534148
181 + 31533967 = 31534148
199 + 31533949 = 31534148
229 + 31533919 = 31534148
277 + 31533871 = 31534148
379 + 31533769 = 31534148

Showing the first eight; more decompositions exist.
