Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89218, here are decompositions:

5 + 89213 = 89218
29 + 89189 = 89218
131 + 89087 = 89218
149 + 89069 = 89218
167 + 89051 = 89218
197 + 89021 = 89218
281 + 88937 = 89218
401 + 88817 = 89218

Showing the first eight; more decompositions exist.
