Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050428, here are decompositions:

7 + 1050421 = 1050428
37 + 1050391 = 1050428
61 + 1050367 = 1050428
79 + 1050349 = 1050428
97 + 1050331 = 1050428
199 + 1050229 = 1050428
277 + 1050151 = 1050428
349 + 1050079 = 1050428

Showing the first eight; more decompositions exist.
