Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20924, here are decompositions:

3 + 20921 = 20924
37 + 20887 = 20924
67 + 20857 = 20924
151 + 20773 = 20924
181 + 20743 = 20924
193 + 20731 = 20924
283 + 20641 = 20924
313 + 20611 = 20924

Showing the first eight; more decompositions exist.
