Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463898, here are decompositions:

5 + 31463893 = 31463898
7 + 31463891 = 31463898
19 + 31463879 = 31463898
41 + 31463857 = 31463898
71 + 31463827 = 31463898
101 + 31463797 = 31463898
131 + 31463767 = 31463898
139 + 31463759 = 31463898

Showing the first eight; more decompositions exist.
