Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1944, here are decompositions:

11 + 1933 = 1944
13 + 1931 = 1944
31 + 1913 = 1944
37 + 1907 = 1944
43 + 1901 = 1944
67 + 1877 = 1944
71 + 1873 = 1944
73 + 1871 = 1944

Showing the first eight; more decompositions exist.
