Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534290, here are decompositions:

19 + 31534271 = 31534290
43 + 31534247 = 31534290
59 + 31534231 = 31534290
103 + 31534187 = 31534290
107 + 31534183 = 31534290
149 + 31534141 = 31534290
173 + 31534117 = 31534290
211 + 31534079 = 31534290

Showing the first eight; more decompositions exist.
