Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662340, here are decompositions:

3 + 8662337 = 8662340
13 + 8662327 = 8662340
61 + 8662279 = 8662340
67 + 8662273 = 8662340
97 + 8662243 = 8662340
139 + 8662201 = 8662340
151 + 8662189 = 8662340
163 + 8662177 = 8662340

Showing the first eight; more decompositions exist.
