Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18950, here are decompositions:

3 + 18947 = 18950
31 + 18919 = 18950
37 + 18913 = 18950
157 + 18793 = 18950
163 + 18787 = 18950
193 + 18757 = 18950
271 + 18679 = 18950
313 + 18637 = 18950

Showing the first eight; more decompositions exist.
