Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616378, here are decompositions:

5 + 8616373 = 8616378
7 + 8616371 = 8616378
41 + 8616337 = 8616378
59 + 8616319 = 8616378
79 + 8616299 = 8616378
97 + 8616281 = 8616378
107 + 8616271 = 8616378
131 + 8616247 = 8616378

Showing the first eight; more decompositions exist.
