Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671698, here are decompositions:

29 + 8671669 = 8671698
59 + 8671639 = 8671698
67 + 8671631 = 8671698
109 + 8671589 = 8671698
149 + 8671549 = 8671698
179 + 8671519 = 8671698
181 + 8671517 = 8671698
197 + 8671501 = 8671698

Showing the first eight; more decompositions exist.
