Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749618, here are decompositions:

5 + 8749613 = 8749618
11 + 8749607 = 8749618
29 + 8749589 = 8749618
47 + 8749571 = 8749618
149 + 8749469 = 8749618
167 + 8749451 = 8749618
179 + 8749439 = 8749618
197 + 8749421 = 8749618

Showing the first eight; more decompositions exist.
