Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648438, here are decompositions:

67 + 8648371 = 8648438
199 + 8648239 = 8648438
307 + 8648131 = 8648438
541 + 8647897 = 8648438
619 + 8647819 = 8648438
727 + 8647711 = 8648438
739 + 8647699 = 8648438
859 + 8647579 = 8648438

Showing the first eight; more decompositions exist.
