Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514844, here are decompositions:

5 + 31514839 = 31514844
7 + 31514837 = 31514844
61 + 31514783 = 31514844
73 + 31514771 = 31514844
103 + 31514741 = 31514844
113 + 31514731 = 31514844
157 + 31514687 = 31514844
173 + 31514671 = 31514844

Showing the first eight; more decompositions exist.
