Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619844, here are decompositions:

47 + 8619797 = 8619844
53 + 8619791 = 8619844
71 + 8619773 = 8619844
131 + 8619713 = 8619844
251 + 8619593 = 8619844
257 + 8619587 = 8619844
293 + 8619551 = 8619844
353 + 8619491 = 8619844

Showing the first eight; more decompositions exist.
