Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18896, here are decompositions:

37 + 18859 = 18896
103 + 18793 = 18896
109 + 18787 = 18896
139 + 18757 = 18896
313 + 18583 = 18896
373 + 18523 = 18896
379 + 18517 = 18896
439 + 18457 = 18896

Showing the first eight; more decompositions exist.
