Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514204, here are decompositions:

13 + 31514191 = 31514204
61 + 31514143 = 31514204
103 + 31514101 = 31514204
181 + 31514023 = 31514204
277 + 31513927 = 31514204
313 + 31513891 = 31514204
331 + 31513873 = 31514204
373 + 31513831 = 31514204

Showing the first eight; more decompositions exist.
