Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18602, here are decompositions:

19 + 18583 = 18602
61 + 18541 = 18602
79 + 18523 = 18602
109 + 18493 = 18602
151 + 18451 = 18602
163 + 18439 = 18602
223 + 18379 = 18602
313 + 18289 = 18602

Showing the first eight; more decompositions exist.
