Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619636, here are decompositions:

13 + 8619623 = 8619636
43 + 8619593 = 8619636
97 + 8619539 = 8619636
127 + 8619509 = 8619636
163 + 8619473 = 8619636
167 + 8619469 = 8619636
197 + 8619439 = 8619636
199 + 8619437 = 8619636

Showing the first eight; more decompositions exist.
