Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619624, here are decompositions:

23 + 8619601 = 8619624
31 + 8619593 = 8619624
37 + 8619587 = 8619624
73 + 8619551 = 8619624
113 + 8619511 = 8619624
151 + 8619473 = 8619624
163 + 8619461 = 8619624
191 + 8619433 = 8619624

Showing the first eight; more decompositions exist.
