Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463850, here are decompositions:

7 + 31463843 = 31463850
23 + 31463827 = 31463850
43 + 31463807 = 31463850
53 + 31463797 = 31463850
71 + 31463779 = 31463850
83 + 31463767 = 31463850
107 + 31463743 = 31463850
137 + 31463713 = 31463850

Showing the first eight; more decompositions exist.
