Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463856, here are decompositions:

7 + 31463849 = 31463856
13 + 31463843 = 31463856
29 + 31463827 = 31463856
59 + 31463797 = 31463856
89 + 31463767 = 31463856
97 + 31463759 = 31463856
113 + 31463743 = 31463856
139 + 31463717 = 31463856

Showing the first eight; more decompositions exist.
