Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620508, here are decompositions:

79 + 8620429 = 8620508
139 + 8620369 = 8620508
181 + 8620327 = 8620508
241 + 8620267 = 8620508
277 + 8620231 = 8620508
349 + 8620159 = 8620508
367 + 8620141 = 8620508
397 + 8620111 = 8620508

Showing the first eight; more decompositions exist.
