Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534182, here are decompositions:

13 + 31534169 = 31534182
41 + 31534141 = 31534182
61 + 31534121 = 31534182
79 + 31534103 = 31534182
103 + 31534079 = 31534182
109 + 31534073 = 31534182
131 + 31534051 = 31534182
149 + 31534033 = 31534182

Showing the first eight; more decompositions exist.
