Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642948, here are decompositions:

37 + 8642911 = 8642948
109 + 8642839 = 8642948
367 + 8642581 = 8642948
439 + 8642509 = 8642948
499 + 8642449 = 8642948
619 + 8642329 = 8642948
751 + 8642197 = 8642948
829 + 8642119 = 8642948

Showing the first eight; more decompositions exist.
