Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671668, here are decompositions:

29 + 8671639 = 8671668
37 + 8671631 = 8671668
79 + 8671589 = 8671668
149 + 8671519 = 8671668
151 + 8671517 = 8671668
157 + 8671511 = 8671668
167 + 8671501 = 8671668
197 + 8671471 = 8671668

Showing the first eight; more decompositions exist.
