Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28618, here are decompositions:

11 + 28607 = 28618
47 + 28571 = 28618
59 + 28559 = 28618
71 + 28547 = 28618
101 + 28517 = 28618
179 + 28439 = 28618
269 + 28349 = 28618
311 + 28307 = 28618

Showing the first eight; more decompositions exist.
