Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43018, here are decompositions:

5 + 43013 = 43018
29 + 42989 = 43018
89 + 42929 = 43018
179 + 42839 = 43018
197 + 42821 = 43018
251 + 42767 = 43018
281 + 42737 = 43018
317 + 42701 = 43018

Showing the first eight; more decompositions exist.
