Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534212, here are decompositions:

13 + 31534199 = 31534212
29 + 31534183 = 31534212
43 + 31534169 = 31534212
71 + 31534141 = 31534212
109 + 31534103 = 31534212
139 + 31534073 = 31534212
179 + 31534033 = 31534212
233 + 31533979 = 31534212

Showing the first eight; more decompositions exist.
