Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630580, here are decompositions:

61 + 8630519 = 8630580
89 + 8630491 = 8630580
97 + 8630483 = 8630580
103 + 8630477 = 8630580
131 + 8630449 = 8630580
137 + 8630443 = 8630580
163 + 8630417 = 8630580
193 + 8630387 = 8630580

Showing the first eight; more decompositions exist.
