Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622372, here are decompositions:

13 + 8622359 = 8622372
19 + 8622353 = 8622372
29 + 8622343 = 8622372
41 + 8622331 = 8622372
71 + 8622301 = 8622372
79 + 8622293 = 8622372
131 + 8622241 = 8622372
149 + 8622223 = 8622372

Showing the first eight; more decompositions exist.
