Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605372, here are decompositions:

3 + 8605369 = 8605372
11 + 8605361 = 8605372
53 + 8605319 = 8605372
131 + 8605241 = 8605372
311 + 8605061 = 8605372
353 + 8605019 = 8605372
389 + 8604983 = 8605372
509 + 8604863 = 8605372

Showing the first eight; more decompositions exist.
