Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558134, here are decompositions:

5 + 31558129 = 31558134
7 + 31558127 = 31558134
53 + 31558081 = 31558134
61 + 31558073 = 31558134
71 + 31558063 = 31558134
137 + 31557997 = 31558134
151 + 31557983 = 31558134
163 + 31557971 = 31558134

Showing the first eight; more decompositions exist.
