Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534158, here are decompositions:

17 + 31534141 = 31534158
37 + 31534121 = 31534158
41 + 31534117 = 31534158
79 + 31534079 = 31534158
101 + 31534057 = 31534158
107 + 31534051 = 31534158
179 + 31533979 = 31534158
191 + 31533967 = 31534158

Showing the first eight; more decompositions exist.
