Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742618, here are decompositions:

41 + 8742577 = 8742618
47 + 8742571 = 8742618
67 + 8742551 = 8742618
89 + 8742529 = 8742618
107 + 8742511 = 8742618
149 + 8742469 = 8742618
197 + 8742421 = 8742618
239 + 8742379 = 8742618

Showing the first eight; more decompositions exist.
