Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463164, here are decompositions:

3 + 31463161 = 31463164
17 + 31463147 = 31463164
41 + 31463123 = 31463164
101 + 31463063 = 31463164
233 + 31462931 = 31463164
263 + 31462901 = 31463164
353 + 31462811 = 31463164
587 + 31462577 = 31463164

Showing the first eight; more decompositions exist.
