Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690244, here are decompositions:

23 + 8690221 = 8690244
41 + 8690203 = 8690244
53 + 8690191 = 8690244
67 + 8690177 = 8690244
71 + 8690173 = 8690244
127 + 8690117 = 8690244
151 + 8690093 = 8690244
181 + 8690063 = 8690244

Showing the first eight; more decompositions exist.
