Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693490, here are decompositions:

23 + 8693467 = 8693490
31 + 8693459 = 8693490
83 + 8693407 = 8693490
89 + 8693401 = 8693490
103 + 8693387 = 8693490
109 + 8693381 = 8693490
151 + 8693339 = 8693490
163 + 8693327 = 8693490

Showing the first eight; more decompositions exist.
