Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661804, here are decompositions:

5 + 8661799 = 8661804
37 + 8661767 = 8661804
61 + 8661743 = 8661804
71 + 8661733 = 8661804
97 + 8661707 = 8661804
101 + 8661703 = 8661804
131 + 8661673 = 8661804
163 + 8661641 = 8661804

Showing the first eight; more decompositions exist.
