Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021852, here are decompositions:

3 + 1021849 = 1021852
53 + 1021799 = 1021852
59 + 1021793 = 1021852
179 + 1021673 = 1021852
191 + 1021661 = 1021852
281 + 1021571 = 1021852
311 + 1021541 = 1021852
389 + 1021463 = 1021852

Showing the first eight; more decompositions exist.
