Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514244, here are decompositions:

5 + 31514239 = 31514244
23 + 31514221 = 31514244
53 + 31514191 = 31514244
101 + 31514143 = 31514244
131 + 31514113 = 31514244
163 + 31514081 = 31514244
257 + 31513987 = 31514244
277 + 31513967 = 31514244

Showing the first eight; more decompositions exist.
