Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042562, here are decompositions:

43 + 1042519 = 1042562
163 + 1042399 = 1042562
181 + 1042381 = 1042562
193 + 1042369 = 1042562
229 + 1042333 = 1042562
379 + 1042183 = 1042562
421 + 1042141 = 1042562
439 + 1042123 = 1042562

Showing the first eight; more decompositions exist.
