Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051528, here are decompositions:

29 + 1051499 = 1051528
47 + 1051481 = 1051528
59 + 1051469 = 1051528
131 + 1051397 = 1051528
227 + 1051301 = 1051528
251 + 1051277 = 1051528
281 + 1051247 = 1051528
347 + 1051181 = 1051528

Showing the first eight; more decompositions exist.
