Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100218, here are decompositions:

5 + 100213 = 100218
11 + 100207 = 100218
29 + 100189 = 100218
67 + 100151 = 100218
89 + 100129 = 100218
109 + 100109 = 100218
149 + 100069 = 100218
199 + 100019 = 100218

Showing the first eight; more decompositions exist.
