Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104218, here are decompositions:

11 + 104207 = 104218
71 + 104147 = 104218
131 + 104087 = 104218
197 + 104021 = 104218
227 + 103991 = 104218
239 + 103979 = 104218
251 + 103967 = 104218
431 + 103787 = 104218

Showing the first eight; more decompositions exist.
