Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021848, here are decompositions:

11 + 1021837 = 1021848
17 + 1021831 = 1021848
41 + 1021807 = 1021848
71 + 1021777 = 1021848
89 + 1021759 = 1021848
101 + 1021747 = 1021848
137 + 1021711 = 1021848
151 + 1021697 = 1021848

Showing the first eight; more decompositions exist.
