Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514958, here are decompositions:

11 + 31514947 = 31514958
47 + 31514911 = 31514958
89 + 31514869 = 31514958
109 + 31514849 = 31514958
227 + 31514731 = 31514958
269 + 31514689 = 31514958
271 + 31514687 = 31514958
317 + 31514641 = 31514958

Showing the first eight; more decompositions exist.
