Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1896, here are decompositions:

7 + 1889 = 1896
17 + 1879 = 1896
19 + 1877 = 1896
23 + 1873 = 1896
29 + 1867 = 1896
73 + 1823 = 1896
107 + 1789 = 1896
109 + 1787 = 1896

Showing the first eight; more decompositions exist.
