Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660372, here are decompositions:

3 + 8660369 = 8660372
103 + 8660269 = 8660372
109 + 8660263 = 8660372
139 + 8660233 = 8660372
151 + 8660221 = 8660372
211 + 8660161 = 8660372
373 + 8659999 = 8660372
433 + 8659939 = 8660372

Showing the first eight; more decompositions exist.
