Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534344, here are decompositions:

11 + 31534333 = 31534344
43 + 31534301 = 31534344
47 + 31534297 = 31534344
73 + 31534271 = 31534344
97 + 31534247 = 31534344
103 + 31534241 = 31534344
113 + 31534231 = 31534344
157 + 31534187 = 31534344

Showing the first eight; more decompositions exist.
