Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047538, here are decompositions:

5 + 1047533 = 1047538
47 + 1047491 = 1047538
59 + 1047479 = 1047538
71 + 1047467 = 1047538
197 + 1047341 = 1047538
227 + 1047311 = 1047538
257 + 1047281 = 1047538
419 + 1047119 = 1047538

Showing the first eight; more decompositions exist.
