Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514350, here are decompositions:

41 + 31514309 = 31514350
53 + 31514297 = 31514350
59 + 31514291 = 31514350
83 + 31514267 = 31514350
89 + 31514261 = 31514350
191 + 31514159 = 31514350
269 + 31514081 = 31514350
383 + 31513967 = 31514350

Showing the first eight; more decompositions exist.
