Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522990, here are decompositions:

29 + 522961 = 522990
31 + 522959 = 522990
43 + 522947 = 522990
47 + 522943 = 522990
71 + 522919 = 522990
103 + 522887 = 522990
107 + 522883 = 522990
109 + 522881 = 522990

Showing the first eight; more decompositions exist.
