Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19126, here are decompositions:

5 + 19121 = 19126
47 + 19079 = 19126
53 + 19073 = 19126
89 + 19037 = 19126
113 + 19013 = 19126
167 + 18959 = 19126
179 + 18947 = 19126
227 + 18899 = 19126

Showing the first eight; more decompositions exist.
