Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662450, here are decompositions:

3 + 8662447 = 8662450
53 + 8662397 = 8662450
101 + 8662349 = 8662450
107 + 8662343 = 8662450
113 + 8662337 = 8662450
131 + 8662319 = 8662450
191 + 8662259 = 8662450
227 + 8662223 = 8662450

Showing the first eight; more decompositions exist.
