Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660172, here are decompositions:

11 + 8660161 = 8660172
139 + 8660033 = 8660172
173 + 8659999 = 8660172
223 + 8659949 = 8660172
233 + 8659939 = 8660172
251 + 8659921 = 8660172
263 + 8659909 = 8660172
379 + 8659793 = 8660172

Showing the first eight; more decompositions exist.
