Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20762, here are decompositions:

3 + 20759 = 20762
13 + 20749 = 20762
19 + 20743 = 20762
31 + 20731 = 20762
43 + 20719 = 20762
151 + 20611 = 20762
163 + 20599 = 20762
199 + 20563 = 20762

Showing the first eight; more decompositions exist.
