Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719222, here are decompositions:

3 + 8719219 = 8719222
11 + 8719211 = 8719222
23 + 8719199 = 8719222
59 + 8719163 = 8719222
89 + 8719133 = 8719222
173 + 8719049 = 8719222
191 + 8719031 = 8719222
269 + 8718953 = 8719222

Showing the first eight; more decompositions exist.
