Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632228, here are decompositions:

5 + 8632223 = 8632228
41 + 8632187 = 8632228
71 + 8632157 = 8632228
89 + 8632139 = 8632228
251 + 8631977 = 8632228
317 + 8631911 = 8632228
347 + 8631881 = 8632228
491 + 8631737 = 8632228

Showing the first eight; more decompositions exist.
