Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690256, here are decompositions:

53 + 8690203 = 8690256
79 + 8690177 = 8690256
83 + 8690173 = 8690256
137 + 8690119 = 8690256
139 + 8690117 = 8690256
163 + 8690093 = 8690256
167 + 8690089 = 8690256
193 + 8690063 = 8690256

Showing the first eight; more decompositions exist.
