Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522890, here are decompositions:

3 + 522887 = 522890
7 + 522883 = 522890
19 + 522871 = 522890
37 + 522853 = 522890
61 + 522829 = 522890
79 + 522811 = 522890
103 + 522787 = 522890
127 + 522763 = 522890

Showing the first eight; more decompositions exist.
