Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534210, here are decompositions:

11 + 31534199 = 31534210
23 + 31534187 = 31534210
41 + 31534169 = 31534210
89 + 31534121 = 31534210
107 + 31534103 = 31534210
131 + 31534079 = 31534210
137 + 31534073 = 31534210
251 + 31533959 = 31534210

Showing the first eight; more decompositions exist.
