Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534188, here are decompositions:

5 + 31534183 = 31534188
19 + 31534169 = 31534188
47 + 31534141 = 31534188
67 + 31534121 = 31534188
71 + 31534117 = 31534188
109 + 31534079 = 31534188
131 + 31534057 = 31534188
137 + 31534051 = 31534188

Showing the first eight; more decompositions exist.
