Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649372, here are decompositions:

5 + 8649367 = 8649372
19 + 8649353 = 8649372
23 + 8649349 = 8649372
29 + 8649343 = 8649372
41 + 8649331 = 8649372
73 + 8649299 = 8649372
79 + 8649293 = 8649372
89 + 8649283 = 8649372

Showing the first eight; more decompositions exist.
