Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661464, here are decompositions:

3 + 8661461 = 8661464
37 + 8661427 = 8661464
211 + 8661253 = 8661464
223 + 8661241 = 8661464
241 + 8661223 = 8661464
271 + 8661193 = 8661464
283 + 8661181 = 8661464
421 + 8661043 = 8661464

Showing the first eight; more decompositions exist.
