Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521930, here are decompositions:

7 + 521923 = 521930
43 + 521887 = 521930
61 + 521869 = 521930
139 + 521791 = 521930
163 + 521767 = 521930
181 + 521749 = 521930
223 + 521707 = 521930
271 + 521659 = 521930

Showing the first eight; more decompositions exist.
