Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660488, here are decompositions:

101 + 8660387 = 8660488
107 + 8660381 = 8660488
149 + 8660339 = 8660488
191 + 8660297 = 8660488
197 + 8660291 = 8660488
311 + 8660177 = 8660488
401 + 8660087 = 8660488
449 + 8660039 = 8660488

Showing the first eight; more decompositions exist.
