Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21032, here are decompositions:

13 + 21019 = 21032
19 + 21013 = 21032
31 + 21001 = 21032
73 + 20959 = 21032
103 + 20929 = 21032
223 + 20809 = 21032
283 + 20749 = 21032
313 + 20719 = 21032

Showing the first eight; more decompositions exist.
