Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521946, here are decompositions:

17 + 521929 = 521946
23 + 521923 = 521946
43 + 521903 = 521946
59 + 521887 = 521946
67 + 521879 = 521946
127 + 521819 = 521946
137 + 521809 = 521946
157 + 521789 = 521946

Showing the first eight; more decompositions exist.
