Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463424, here are decompositions:

17 + 31463407 = 31463424
37 + 31463387 = 31463424
61 + 31463363 = 31463424
71 + 31463353 = 31463424
103 + 31463321 = 31463424
107 + 31463317 = 31463424
163 + 31463261 = 31463424
197 + 31463227 = 31463424

Showing the first eight; more decompositions exist.
