Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660002, here are decompositions:

3 + 8659999 = 8660002
5 + 8659997 = 8660002
53 + 8659949 = 8660002
89 + 8659913 = 8660002
191 + 8659811 = 8660002
233 + 8659769 = 8660002
311 + 8659691 = 8660002
359 + 8659643 = 8660002

Showing the first eight; more decompositions exist.
