Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661662, here are decompositions:

19 + 8661643 = 8661662
109 + 8661553 = 8661662
193 + 8661469 = 8661662
223 + 8661439 = 8661662
409 + 8661253 = 8661662
421 + 8661241 = 8661662
439 + 8661223 = 8661662
601 + 8661061 = 8661662

Showing the first eight; more decompositions exist.
