Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005528, here are decompositions:

47 + 1005481 = 1005528
61 + 1005467 = 1005528
71 + 1005457 = 1005528
89 + 1005439 = 1005528
101 + 1005427 = 1005528
137 + 1005391 = 1005528
157 + 1005371 = 1005528
179 + 1005349 = 1005528

Showing the first eight; more decompositions exist.
