Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719458, here are decompositions:

17 + 8719441 = 8719458
37 + 8719421 = 8719458
67 + 8719391 = 8719458
79 + 8719379 = 8719458
109 + 8719349 = 8719458
131 + 8719327 = 8719458
151 + 8719307 = 8719458
157 + 8719301 = 8719458

Showing the first eight; more decompositions exist.
