Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049428, here are decompositions:

41 + 1049387 = 1049428
89 + 1049339 = 1049428
131 + 1049297 = 1049428
227 + 1049201 = 1049428
251 + 1049177 = 1049428
257 + 1049171 = 1049428
311 + 1049117 = 1049428
389 + 1049039 = 1049428

Showing the first eight; more decompositions exist.
