Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19042, here are decompositions:

5 + 19037 = 19042
11 + 19031 = 19042
29 + 19013 = 19042
41 + 19001 = 19042
83 + 18959 = 19042
131 + 18911 = 19042
173 + 18869 = 19042
239 + 18803 = 19042

Showing the first eight; more decompositions exist.
