Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027538, here are decompositions:

19 + 1027519 = 1027538
67 + 1027471 = 1027538
79 + 1027459 = 1027538
181 + 1027357 = 1027538
277 + 1027261 = 1027538
331 + 1027207 = 1027538
349 + 1027189 = 1027538
409 + 1027129 = 1027538

Showing the first eight; more decompositions exist.
