Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614428, here are decompositions:

19 + 8614409 = 8614428
47 + 8614381 = 8614428
59 + 8614369 = 8614428
71 + 8614357 = 8614428
101 + 8614327 = 8614428
131 + 8614297 = 8614428
167 + 8614261 = 8614428
197 + 8614231 = 8614428

Showing the first eight; more decompositions exist.
