Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514914, here are decompositions:

3 + 31514911 = 31514914
131 + 31514783 = 31514914
173 + 31514741 = 31514914
227 + 31514687 = 31514914
251 + 31514663 = 31514914
401 + 31514513 = 31514914
491 + 31514423 = 31514914
617 + 31514297 = 31514914

Showing the first eight; more decompositions exist.
