Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19036, here are decompositions:

5 + 19031 = 19036
23 + 19013 = 19036
89 + 18947 = 19036
137 + 18899 = 19036
167 + 18869 = 19036
197 + 18839 = 19036
233 + 18803 = 19036
239 + 18797 = 19036

Showing the first eight; more decompositions exist.
