Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748618, here are decompositions:

17 + 8748601 = 8748618
19 + 8748599 = 8748618
29 + 8748589 = 8748618
31 + 8748587 = 8748618
37 + 8748581 = 8748618
149 + 8748469 = 8748618
199 + 8748419 = 8748618
251 + 8748367 = 8748618

Showing the first eight; more decompositions exist.
