Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042526, here are decompositions:

3 + 1042523 = 1042526
7 + 1042519 = 1042526
127 + 1042399 = 1042526
157 + 1042369 = 1042526
193 + 1042333 = 1042526
283 + 1042243 = 1042526
439 + 1042087 = 1042526
487 + 1042039 = 1042526

Showing the first eight; more decompositions exist.
