Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519914, here are decompositions:

5 + 31519909 = 31519914
37 + 31519877 = 31519914
71 + 31519843 = 31519914
113 + 31519801 = 31519914
131 + 31519783 = 31519914
211 + 31519703 = 31519914
227 + 31519687 = 31519914
241 + 31519673 = 31519914

Showing the first eight; more decompositions exist.
