Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514802, here are decompositions:

13 + 31514789 = 31514802
19 + 31514783 = 31514802
31 + 31514771 = 31514802
61 + 31514741 = 31514802
71 + 31514731 = 31514802
113 + 31514689 = 31514802
131 + 31514671 = 31514802
139 + 31514663 = 31514802

Showing the first eight; more decompositions exist.
