Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619540, here are decompositions:

29 + 8619511 = 8619540
31 + 8619509 = 8619540
67 + 8619473 = 8619540
71 + 8619469 = 8619540
79 + 8619461 = 8619540
101 + 8619439 = 8619540
103 + 8619437 = 8619540
107 + 8619433 = 8619540

Showing the first eight; more decompositions exist.
