Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18968, here are decompositions:

109 + 18859 = 18968
181 + 18787 = 18968
211 + 18757 = 18968
277 + 18691 = 18968
307 + 18661 = 18968
331 + 18637 = 18968
487 + 18481 = 18968
541 + 18427 = 18968

Showing the first eight; more decompositions exist.
