Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049478, here are decompositions:

5 + 1049473 = 1049478
7 + 1049471 = 1049478
19 + 1049459 = 1049478
41 + 1049437 = 1049478
139 + 1049339 = 1049478
181 + 1049297 = 1049478
197 + 1049281 = 1049478
239 + 1049239 = 1049478

Showing the first eight; more decompositions exist.
