Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042512, here are decompositions:

43 + 1042469 = 1042512
61 + 1042451 = 1042512
73 + 1042439 = 1042512
113 + 1042399 = 1042512
131 + 1042381 = 1042512
139 + 1042373 = 1042512
179 + 1042333 = 1042512
181 + 1042331 = 1042512

Showing the first eight; more decompositions exist.
