Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631460, here are decompositions:

59 + 8631401 = 8631460
191 + 8631269 = 8631460
269 + 8631191 = 8631460
293 + 8631167 = 8631460
419 + 8631041 = 8631460
443 + 8631017 = 8631460
449 + 8631011 = 8631460
557 + 8630903 = 8631460

Showing the first eight; more decompositions exist.
