Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621360, here are decompositions:

61 + 8621299 = 8621360
79 + 8621281 = 8621360
151 + 8621209 = 8621360
271 + 8621089 = 8621360
277 + 8621083 = 8621360
283 + 8621077 = 8621360
313 + 8621047 = 8621360
367 + 8620993 = 8621360

Showing the first eight; more decompositions exist.
