Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534134, here are decompositions:

13 + 31534121 = 31534134
17 + 31534117 = 31534134
31 + 31534103 = 31534134
61 + 31534073 = 31534134
67 + 31534067 = 31534134
83 + 31534051 = 31534134
101 + 31534033 = 31534134
167 + 31533967 = 31534134

Showing the first eight; more decompositions exist.
