Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620624, here are decompositions:

3 + 8620621 = 8620624
53 + 8620571 = 8620624
71 + 8620553 = 8620624
263 + 8620361 = 8620624
317 + 8620307 = 8620624
347 + 8620277 = 8620624
491 + 8620133 = 8620624
503 + 8620121 = 8620624

Showing the first eight; more decompositions exist.
