Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514250, here are decompositions:

11 + 31514239 = 31514250
29 + 31514221 = 31514250
59 + 31514191 = 31514250
101 + 31514149 = 31514250
107 + 31514143 = 31514250
137 + 31514113 = 31514250
149 + 31514101 = 31514250
191 + 31514059 = 31514250

Showing the first eight; more decompositions exist.
