Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18702, here are decompositions:

11 + 18691 = 18702
23 + 18679 = 18702
31 + 18671 = 18702
41 + 18661 = 18702
109 + 18593 = 18702
149 + 18553 = 18702
163 + 18539 = 18702
179 + 18523 = 18702

Showing the first eight; more decompositions exist.
