Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620748, here are decompositions:

61 + 8620687 = 8620748
109 + 8620639 = 8620748
127 + 8620621 = 8620748
181 + 8620567 = 8620748
379 + 8620369 = 8620748
421 + 8620327 = 8620748
607 + 8620141 = 8620748
751 + 8619997 = 8620748

Showing the first eight; more decompositions exist.
