Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661030, here are decompositions:

29 + 8661001 = 8661030
43 + 8660987 = 8661030
47 + 8660983 = 8661030
61 + 8660969 = 8661030
83 + 8660947 = 8661030
97 + 8660933 = 8661030
101 + 8660929 = 8661030
109 + 8660921 = 8661030

Showing the first eight; more decompositions exist.
