Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661774, here are decompositions:

5 + 8661769 = 8661774
7 + 8661767 = 8661774
31 + 8661743 = 8661774
41 + 8661733 = 8661774
47 + 8661727 = 8661774
67 + 8661707 = 8661774
71 + 8661703 = 8661774
101 + 8661673 = 8661774

Showing the first eight; more decompositions exist.
