Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21932, here are decompositions:

3 + 21929 = 21932
61 + 21871 = 21932
73 + 21859 = 21932
181 + 21751 = 21932
193 + 21739 = 21932
271 + 21661 = 21932
283 + 21649 = 21932
331 + 21601 = 21932

Showing the first eight; more decompositions exist.
