Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482234, here are decompositions:

5 + 31482229 = 31482234
61 + 31482173 = 31482234
67 + 31482167 = 31482234
131 + 31482103 = 31482234
137 + 31482097 = 31482234
151 + 31482083 = 31482234
167 + 31482067 = 31482234
191 + 31482043 = 31482234

Showing the first eight; more decompositions exist.
