Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663120, here are decompositions:

3 + 8663117 = 8663120
19 + 8663101 = 8663120
31 + 8663089 = 8663120
97 + 8663023 = 8663120
157 + 8662963 = 8663120
181 + 8662939 = 8663120
229 + 8662891 = 8663120
313 + 8662807 = 8663120

Showing the first eight; more decompositions exist.
