Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82618, here are decompositions:

5 + 82613 = 82618
17 + 82601 = 82618
47 + 82571 = 82618
59 + 82559 = 82618
89 + 82529 = 82618
131 + 82487 = 82618
149 + 82469 = 82618
197 + 82421 = 82618

Showing the first eight; more decompositions exist.
