Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042356, here are decompositions:

23 + 1042333 = 1042356
47 + 1042309 = 1042356
83 + 1042273 = 1042356
89 + 1042267 = 1042356
97 + 1042259 = 1042356
113 + 1042243 = 1042356
163 + 1042193 = 1042356
173 + 1042183 = 1042356

Showing the first eight; more decompositions exist.
