Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632142, here are decompositions:

3 + 8632139 = 8632142
19 + 8632123 = 8632142
61 + 8632081 = 8632142
73 + 8632069 = 8632142
139 + 8632003 = 8632142
163 + 8631979 = 8632142
199 + 8631943 = 8632142
373 + 8631769 = 8632142

Showing the first eight; more decompositions exist.
