Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660530, here are decompositions:

3 + 8660527 = 8660530
23 + 8660507 = 8660530
107 + 8660423 = 8660530
149 + 8660381 = 8660530
191 + 8660339 = 8660530
233 + 8660297 = 8660530
239 + 8660291 = 8660530
353 + 8660177 = 8660530

Showing the first eight; more decompositions exist.
