Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613372, here are decompositions:

23 + 8613349 = 8613372
43 + 8613329 = 8613372
73 + 8613299 = 8613372
151 + 8613221 = 8613372
191 + 8613181 = 8613372
211 + 8613161 = 8613372
223 + 8613149 = 8613372
281 + 8613091 = 8613372

Showing the first eight; more decompositions exist.
