Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18914, here are decompositions:

3 + 18911 = 18914
127 + 18787 = 18914
157 + 18757 = 18914
223 + 18691 = 18914
277 + 18637 = 18914
331 + 18583 = 18914
373 + 18541 = 18914
397 + 18517 = 18914

Showing the first eight; more decompositions exist.
