Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514698, here are decompositions:

11 + 31514687 = 31514698
71 + 31514627 = 31514698
269 + 31514429 = 31514698
389 + 31514309 = 31514698
401 + 31514297 = 31514698
431 + 31514267 = 31514698
617 + 31514081 = 31514698
821 + 31513877 = 31514698

Showing the first eight; more decompositions exist.
