Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749222, here are decompositions:

3 + 8749219 = 8749222
23 + 8749199 = 8749222
59 + 8749163 = 8749222
71 + 8749151 = 8749222
89 + 8749133 = 8749222
101 + 8749121 = 8749222
173 + 8749049 = 8749222
233 + 8748989 = 8749222

Showing the first eight; more decompositions exist.
