Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600440, here are decompositions:

3 + 8600437 = 8600440
29 + 8600411 = 8600440
41 + 8600399 = 8600440
47 + 8600393 = 8600440
131 + 8600309 = 8600440
227 + 8600213 = 8600440
269 + 8600171 = 8600440
347 + 8600093 = 8600440

Showing the first eight; more decompositions exist.
