Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672164, here are decompositions:

3 + 8672161 = 8672164
47 + 8672117 = 8672164
101 + 8672063 = 8672164
173 + 8671991 = 8672164
197 + 8671967 = 8672164
227 + 8671937 = 8672164
257 + 8671907 = 8672164
353 + 8671811 = 8672164

Showing the first eight; more decompositions exist.
