Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84218, here are decompositions:

7 + 84211 = 84218
19 + 84199 = 84218
37 + 84181 = 84218
97 + 84121 = 84218
151 + 84067 = 84218
157 + 84061 = 84218
307 + 83911 = 84218
349 + 83869 = 84218

Showing the first eight; more decompositions exist.
