Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514274, here are decompositions:

7 + 31514267 = 31514274
13 + 31514261 = 31514274
53 + 31514221 = 31514274
83 + 31514191 = 31514274
131 + 31514143 = 31514274
173 + 31514101 = 31514274
193 + 31514081 = 31514274
251 + 31514023 = 31514274

Showing the first eight; more decompositions exist.
