Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661084, here are decompositions:

23 + 8661061 = 8661084
37 + 8661047 = 8661084
41 + 8661043 = 8661084
83 + 8661001 = 8661084
97 + 8660987 = 8661084
101 + 8660983 = 8661084
137 + 8660947 = 8661084
151 + 8660933 = 8661084

Showing the first eight; more decompositions exist.
