Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671162, here are decompositions:

11 + 8671151 = 8671162
29 + 8671133 = 8671162
131 + 8671031 = 8671162
173 + 8670989 = 8671162
293 + 8670869 = 8671162
389 + 8670773 = 8671162
419 + 8670743 = 8671162
449 + 8670713 = 8671162

Showing the first eight; more decompositions exist.
