Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661924, here are decompositions:

23 + 8661901 = 8661924
41 + 8661883 = 8661924
43 + 8661881 = 8661924
53 + 8661871 = 8661924
83 + 8661841 = 8661924
157 + 8661767 = 8661924
181 + 8661743 = 8661924
191 + 8661733 = 8661924

Showing the first eight; more decompositions exist.
