Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20362, here are decompositions:

3 + 20359 = 20362
5 + 20357 = 20362
29 + 20333 = 20362
101 + 20261 = 20362
113 + 20249 = 20362
131 + 20231 = 20362
179 + 20183 = 20362
233 + 20129 = 20362

Showing the first eight; more decompositions exist.
