Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18734, here are decompositions:

3 + 18731 = 18734
43 + 18691 = 18734
73 + 18661 = 18734
97 + 18637 = 18734
151 + 18583 = 18734
181 + 18553 = 18734
193 + 18541 = 18734
211 + 18523 = 18734

Showing the first eight; more decompositions exist.
