Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042738, here are decompositions:

5 + 1042733 = 1042738
29 + 1042709 = 1042738
107 + 1042631 = 1042738
131 + 1042607 = 1042738
167 + 1042571 = 1042738
251 + 1042487 = 1042738
269 + 1042469 = 1042738
311 + 1042427 = 1042738

Showing the first eight; more decompositions exist.
