Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663142, here are decompositions:

23 + 8663119 = 8663142
41 + 8663101 = 8663142
43 + 8663099 = 8663142
53 + 8663089 = 8663142
71 + 8663071 = 8663142
139 + 8663003 = 8663142
151 + 8662991 = 8663142
179 + 8662963 = 8663142

Showing the first eight; more decompositions exist.
