Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671264, here are decompositions:

71 + 8671193 = 8671264
113 + 8671151 = 8671264
131 + 8671133 = 8671264
137 + 8671127 = 8671264
167 + 8671097 = 8671264
197 + 8671067 = 8671264
233 + 8671031 = 8671264
257 + 8671007 = 8671264

Showing the first eight; more decompositions exist.
