Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021948, here are decompositions:

29 + 1021919 = 1021948
41 + 1021907 = 1021948
149 + 1021799 = 1021948
251 + 1021697 = 1021948
461 + 1021487 = 1021948
491 + 1021457 = 1021948
617 + 1021331 = 1021948
647 + 1021301 = 1021948

Showing the first eight; more decompositions exist.
