Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749422, here are decompositions:

5 + 8749417 = 8749422
79 + 8749343 = 8749422
113 + 8749309 = 8749422
179 + 8749243 = 8749422
193 + 8749229 = 8749422
223 + 8749199 = 8749422
271 + 8749151 = 8749422
281 + 8749141 = 8749422

Showing the first eight; more decompositions exist.
