Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534356, here are decompositions:

13 + 31534343 = 31534356
23 + 31534333 = 31534356
59 + 31534297 = 31534356
109 + 31534247 = 31534356
157 + 31534199 = 31534356
173 + 31534183 = 31534356
239 + 31534117 = 31534356
277 + 31534079 = 31534356

Showing the first eight; more decompositions exist.
