Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18782, here are decompositions:

103 + 18679 = 18782
199 + 18583 = 18782
229 + 18553 = 18782
241 + 18541 = 18782
331 + 18451 = 18782
349 + 18433 = 18782
571 + 18211 = 18782
601 + 18181 = 18782

Showing the first eight; more decompositions exist.
