Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021902, here are decompositions:

5 + 1021897 = 1021902
23 + 1021879 = 1021902
41 + 1021861 = 1021902
53 + 1021849 = 1021902
71 + 1021831 = 1021902
103 + 1021799 = 1021902
109 + 1021793 = 1021902
149 + 1021753 = 1021902

Showing the first eight; more decompositions exist.
