Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18962, here are decompositions:

3 + 18959 = 18962
43 + 18919 = 18962
103 + 18859 = 18962
271 + 18691 = 18962
283 + 18679 = 18962
379 + 18583 = 18962
409 + 18553 = 18962
421 + 18541 = 18962

Showing the first eight; more decompositions exist.
