Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632240, here are decompositions:

3 + 8632237 = 8632240
17 + 8632223 = 8632240
53 + 8632187 = 8632240
83 + 8632157 = 8632240
101 + 8632139 = 8632240
107 + 8632133 = 8632240
137 + 8632103 = 8632240
263 + 8631977 = 8632240

Showing the first eight; more decompositions exist.
