Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2144, here are decompositions:

3 + 2141 = 2144
7 + 2137 = 2144
13 + 2131 = 2144
31 + 2113 = 2144
61 + 2083 = 2144
127 + 2017 = 2144
151 + 1993 = 2144
157 + 1987 = 2144

Showing the first eight; more decompositions exist.
