Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620580, here are decompositions:

13 + 8620567 = 8620580
37 + 8620543 = 8620580
151 + 8620429 = 8620580
211 + 8620369 = 8620580
313 + 8620267 = 8620580
349 + 8620231 = 8620580
421 + 8620159 = 8620580
439 + 8620141 = 8620580

Showing the first eight; more decompositions exist.
