Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022548, here are decompositions:

17 + 1022531 = 1022548
29 + 1022519 = 1022548
41 + 1022507 = 1022548
47 + 1022501 = 1022548
167 + 1022381 = 1022548
257 + 1022291 = 1022548
311 + 1022237 = 1022548
347 + 1022201 = 1022548

Showing the first eight; more decompositions exist.
