Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18634, here are decompositions:

17 + 18617 = 18634
41 + 18593 = 18634
47 + 18587 = 18634
113 + 18521 = 18634
131 + 18503 = 18634
173 + 18461 = 18634
191 + 18443 = 18634
233 + 18401 = 18634

Showing the first eight; more decompositions exist.
