Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18662, here are decompositions:

79 + 18583 = 18662
109 + 18553 = 18662
139 + 18523 = 18662
181 + 18481 = 18662
211 + 18451 = 18662
223 + 18439 = 18662
229 + 18433 = 18662
283 + 18379 = 18662

Showing the first eight; more decompositions exist.
