Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004538, here are decompositions:

11 + 1004527 = 1004538
37 + 1004501 = 1004538
61 + 1004477 = 1004538
89 + 1004449 = 1004538
97 + 1004441 = 1004538
109 + 1004429 = 1004538
137 + 1004401 = 1004538
167 + 1004371 = 1004538

Showing the first eight; more decompositions exist.
