Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615854, here are decompositions:

5 + 31615849 = 31615854
7 + 31615847 = 31615854
47 + 31615807 = 31615854
71 + 31615783 = 31615854
97 + 31615757 = 31615854
113 + 31615741 = 31615854
191 + 31615663 = 31615854
251 + 31615603 = 31615854

Showing the first eight; more decompositions exist.
