Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603440, here are decompositions:

11 + 8603429 = 8603440
47 + 8603393 = 8603440
59 + 8603381 = 8603440
71 + 8603369 = 8603440
173 + 8603267 = 8603440
191 + 8603249 = 8603440
239 + 8603201 = 8603440
257 + 8603183 = 8603440

Showing the first eight; more decompositions exist.
