Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023156, here are decompositions:

23 + 1023133 = 1023156
73 + 1023083 = 1023156
89 + 1023067 = 1023156
109 + 1023047 = 1023156
137 + 1023019 = 1023156
179 + 1022977 = 1023156
193 + 1022963 = 1023156
223 + 1022933 = 1023156

Showing the first eight; more decompositions exist.
