Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534270, here are decompositions:

23 + 31534247 = 31534270
29 + 31534241 = 31534270
71 + 31534199 = 31534270
83 + 31534187 = 31534270
101 + 31534169 = 31534270
149 + 31534121 = 31534270
167 + 31534103 = 31534270
191 + 31534079 = 31534270

Showing the first eight; more decompositions exist.
