Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671258, here are decompositions:

107 + 8671151 = 8671258
131 + 8671127 = 8671258
191 + 8671067 = 8671258
227 + 8671031 = 8671258
251 + 8671007 = 8671258
269 + 8670989 = 8671258
311 + 8670947 = 8671258
317 + 8670941 = 8671258

Showing the first eight; more decompositions exist.
