Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484164, here are decompositions:

3 + 31484161 = 31484164
71 + 31484093 = 31484164
83 + 31484081 = 31484164
251 + 31483913 = 31484164
281 + 31483883 = 31484164
293 + 31483871 = 31484164
431 + 31483733 = 31484164
587 + 31483577 = 31484164

Showing the first eight; more decompositions exist.
