Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19144, here are decompositions:

3 + 19141 = 19144
5 + 19139 = 19144
23 + 19121 = 19144
71 + 19073 = 19144
107 + 19037 = 19144
113 + 19031 = 19144
131 + 19013 = 19144
197 + 18947 = 19144

Showing the first eight; more decompositions exist.
