Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621036, here are decompositions:

19 + 8621017 = 8621036
43 + 8620993 = 8621036
139 + 8620897 = 8621036
163 + 8620873 = 8621036
313 + 8620723 = 8621036
349 + 8620687 = 8621036
373 + 8620663 = 8621036
397 + 8620639 = 8621036

Showing the first eight; more decompositions exist.
