Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620372, here are decompositions:

3 + 8620369 = 8620372
11 + 8620361 = 8620372
23 + 8620349 = 8620372
83 + 8620289 = 8620372
113 + 8620259 = 8620372
239 + 8620133 = 8620372
251 + 8620121 = 8620372
263 + 8620109 = 8620372

Showing the first eight; more decompositions exist.
