Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514524, here are decompositions:

11 + 31514513 = 31514524
47 + 31514477 = 31514524
101 + 31514423 = 31514524
227 + 31514297 = 31514524
233 + 31514291 = 31514524
257 + 31514267 = 31514524
263 + 31514261 = 31514524
443 + 31514081 = 31514524

Showing the first eight; more decompositions exist.
