Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17802, here are decompositions:

11 + 17791 = 17802
13 + 17789 = 17802
19 + 17783 = 17802
41 + 17761 = 17802
53 + 17749 = 17802
73 + 17729 = 17802
89 + 17713 = 17802
179 + 17623 = 17802

Showing the first eight; more decompositions exist.
