Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042572, here are decompositions:

43 + 1042529 = 1042572
53 + 1042519 = 1042572
103 + 1042469 = 1042572
173 + 1042399 = 1042572
191 + 1042381 = 1042572
199 + 1042373 = 1042572
239 + 1042333 = 1042572
241 + 1042331 = 1042572

Showing the first eight; more decompositions exist.
