Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18610, here are decompositions:

17 + 18593 = 18610
23 + 18587 = 18610
71 + 18539 = 18610
89 + 18521 = 18610
107 + 18503 = 18610
149 + 18461 = 18610
167 + 18443 = 18610
197 + 18413 = 18610

Showing the first eight; more decompositions exist.
