Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514216, here are decompositions:

67 + 31514149 = 31514216
73 + 31514143 = 31514216
103 + 31514113 = 31514216
157 + 31514059 = 31514216
193 + 31514023 = 31514216
229 + 31513987 = 31514216
337 + 31513879 = 31514216
367 + 31513849 = 31514216

Showing the first eight; more decompositions exist.
