Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011528, here are decompositions:

19 + 1011509 = 1011528
97 + 1011431 = 1011528
131 + 1011397 = 1011528
137 + 1011391 = 1011528
151 + 1011377 = 1011528
157 + 1011371 = 1011528
179 + 1011349 = 1011528
197 + 1011331 = 1011528

Showing the first eight; more decompositions exist.
