Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661792, here are decompositions:

23 + 8661769 = 8661792
59 + 8661733 = 8661792
89 + 8661703 = 8661792
103 + 8661689 = 8661792
109 + 8661683 = 8661792
149 + 8661643 = 8661792
151 + 8661641 = 8661792
163 + 8661629 = 8661792

Showing the first eight; more decompositions exist.
