Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620988, here are decompositions:

37 + 8620951 = 8620988
127 + 8620861 = 8620988
241 + 8620747 = 8620988
349 + 8620639 = 8620988
367 + 8620621 = 8620988
421 + 8620567 = 8620988
619 + 8620369 = 8620988
661 + 8620327 = 8620988

Showing the first eight; more decompositions exist.
