Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18302, here are decompositions:

13 + 18289 = 18302
73 + 18229 = 18302
79 + 18223 = 18302
103 + 18199 = 18302
181 + 18121 = 18302
241 + 18061 = 18302
313 + 17989 = 18302
331 + 17971 = 18302

Showing the first eight; more decompositions exist.
