Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631434, here are decompositions:

43 + 8631391 = 8631434
61 + 8631373 = 8631434
67 + 8631367 = 8631434
103 + 8631331 = 8631434
127 + 8631307 = 8631434
151 + 8631283 = 8631434
157 + 8631277 = 8631434
241 + 8631193 = 8631434

Showing the first eight; more decompositions exist.
