Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722342, here are decompositions:

3 + 8722339 = 8722342
11 + 8722331 = 8722342
59 + 8722283 = 8722342
131 + 8722211 = 8722342
149 + 8722193 = 8722342
173 + 8722169 = 8722342
263 + 8722079 = 8722342
353 + 8721989 = 8722342

Showing the first eight; more decompositions exist.
