Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19072, here are decompositions:

3 + 19069 = 19072
41 + 19031 = 19072
59 + 19013 = 19072
71 + 19001 = 19072
113 + 18959 = 19072
173 + 18899 = 19072
233 + 18839 = 19072
269 + 18803 = 19072

Showing the first eight; more decompositions exist.
