Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629388, here are decompositions:

109 + 8629279 = 8629388
379 + 8629009 = 8629388
421 + 8628967 = 8629388
499 + 8628889 = 8629388
541 + 8628847 = 8629388
577 + 8628811 = 8629388
601 + 8628787 = 8629388
661 + 8628727 = 8629388

Showing the first eight; more decompositions exist.
