Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661822, here are decompositions:

23 + 8661799 = 8661822
53 + 8661769 = 8661822
79 + 8661743 = 8661822
89 + 8661733 = 8661822
139 + 8661683 = 8661822
149 + 8661673 = 8661822
179 + 8661643 = 8661822
181 + 8661641 = 8661822

Showing the first eight; more decompositions exist.
