Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534308, here are decompositions:

7 + 31534301 = 31534308
11 + 31534297 = 31534308
37 + 31534271 = 31534308
61 + 31534247 = 31534308
67 + 31534241 = 31534308
109 + 31534199 = 31534308
139 + 31534169 = 31534308
167 + 31534141 = 31534308

Showing the first eight; more decompositions exist.
