Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671222, here are decompositions:

3 + 8671219 = 8671222
29 + 8671193 = 8671222
71 + 8671151 = 8671222
89 + 8671133 = 8671222
191 + 8671031 = 8671222
233 + 8670989 = 8671222
281 + 8670941 = 8671222
353 + 8670869 = 8671222

Showing the first eight; more decompositions exist.
