Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660212, here are decompositions:

23 + 8660189 = 8660212
131 + 8660081 = 8660212
173 + 8660039 = 8660212
179 + 8660033 = 8660212
263 + 8659949 = 8660212
401 + 8659811 = 8660212
419 + 8659793 = 8660212
443 + 8659769 = 8660212

Showing the first eight; more decompositions exist.
