Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017542, here are decompositions:

3 + 1017539 = 1017542
61 + 1017481 = 1017542
103 + 1017439 = 1017542
151 + 1017391 = 1017542
181 + 1017361 = 1017542
223 + 1017319 = 1017542
241 + 1017301 = 1017542
349 + 1017193 = 1017542

Showing the first eight; more decompositions exist.
