Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514304, here are decompositions:

7 + 31514297 = 31514304
13 + 31514291 = 31514304
37 + 31514267 = 31514304
43 + 31514261 = 31514304
83 + 31514221 = 31514304
113 + 31514191 = 31514304
191 + 31514113 = 31514304
223 + 31514081 = 31514304

Showing the first eight; more decompositions exist.
