Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2892, here are decompositions:

5 + 2887 = 2892
13 + 2879 = 2892
31 + 2861 = 2892
41 + 2851 = 2892
59 + 2833 = 2892
73 + 2819 = 2892
89 + 2803 = 2892
101 + 2791 = 2892

Showing the first eight; more decompositions exist.
