Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031528, here are decompositions:

7 + 1031521 = 1031528
67 + 1031461 = 1031528
97 + 1031431 = 1031528
181 + 1031347 = 1031528
229 + 1031299 = 1031528
367 + 1031161 = 1031528
409 + 1031119 = 1031528
541 + 1030987 = 1031528

Showing the first eight; more decompositions exist.
