Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534350, here are decompositions:

7 + 31534343 = 31534350
17 + 31534333 = 31534350
53 + 31534297 = 31534350
79 + 31534271 = 31534350
103 + 31534247 = 31534350
109 + 31534241 = 31534350
151 + 31534199 = 31534350
163 + 31534187 = 31534350

Showing the first eight; more decompositions exist.
