Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631524, here are decompositions:

7 + 8631517 = 8631524
73 + 8631451 = 8631524
151 + 8631373 = 8631524
157 + 8631367 = 8631524
193 + 8631331 = 8631524
241 + 8631283 = 8631524
277 + 8631247 = 8631524
331 + 8631193 = 8631524

Showing the first eight; more decompositions exist.
