Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693440, here are decompositions:

53 + 8693387 = 8693440
59 + 8693381 = 8693440
71 + 8693369 = 8693440
101 + 8693339 = 8693440
113 + 8693327 = 8693440
131 + 8693309 = 8693440
227 + 8693213 = 8693440
233 + 8693207 = 8693440

Showing the first eight; more decompositions exist.
