Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750428, here are decompositions:

41 + 8750387 = 8750428
59 + 8750369 = 8750428
107 + 8750321 = 8750428
179 + 8750249 = 8750428
251 + 8750177 = 8750428
257 + 8750171 = 8750428
359 + 8750069 = 8750428
389 + 8750039 = 8750428

Showing the first eight; more decompositions exist.
