Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630144, here are decompositions:

31 + 8630113 = 8630144
73 + 8630071 = 8630144
163 + 8629981 = 8630144
181 + 8629963 = 8630144
277 + 8629867 = 8630144
331 + 8629813 = 8630144
373 + 8629771 = 8630144
433 + 8629711 = 8630144

Showing the first eight; more decompositions exist.
