Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719386, here are decompositions:

7 + 8719379 = 8719386
19 + 8719367 = 8719386
37 + 8719349 = 8719386
59 + 8719327 = 8719386
79 + 8719307 = 8719386
83 + 8719303 = 8719386
97 + 8719289 = 8719386
113 + 8719273 = 8719386

Showing the first eight; more decompositions exist.
