Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661004, here are decompositions:

3 + 8661001 = 8661004
17 + 8660987 = 8661004
71 + 8660933 = 8661004
83 + 8660921 = 8661004
113 + 8660891 = 8661004
251 + 8660753 = 8661004
257 + 8660747 = 8661004
263 + 8660741 = 8661004

Showing the first eight; more decompositions exist.
