Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662320, here are decompositions:

41 + 8662279 = 8662320
47 + 8662273 = 8662320
61 + 8662259 = 8662320
71 + 8662249 = 8662320
97 + 8662223 = 8662320
101 + 8662219 = 8662320
103 + 8662217 = 8662320
131 + 8662189 = 8662320

Showing the first eight; more decompositions exist.
