Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620986, here are decompositions:

13 + 8620973 = 8620986
37 + 8620949 = 8620986
43 + 8620943 = 8620986
89 + 8620897 = 8620986
113 + 8620873 = 8620986
139 + 8620847 = 8620986
229 + 8620757 = 8620986
239 + 8620747 = 8620986

Showing the first eight; more decompositions exist.
