Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021884, here are decompositions:

5 + 1021879 = 1021884
23 + 1021861 = 1021884
47 + 1021837 = 1021884
53 + 1021831 = 1021884
107 + 1021777 = 1021884
131 + 1021753 = 1021884
137 + 1021747 = 1021884
173 + 1021711 = 1021884

Showing the first eight; more decompositions exist.
