Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040538, here are decompositions:

7 + 1040531 = 1040538
17 + 1040521 = 1040538
89 + 1040449 = 1040538
127 + 1040411 = 1040538
131 + 1040407 = 1040538
151 + 1040387 = 1040538
157 + 1040381 = 1040538
167 + 1040371 = 1040538

Showing the first eight; more decompositions exist.
