Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2904, here are decompositions:

7 + 2897 = 2904
17 + 2887 = 2904
43 + 2861 = 2904
47 + 2857 = 2904
53 + 2851 = 2904
61 + 2843 = 2904
67 + 2837 = 2904
71 + 2833 = 2904

Showing the first eight; more decompositions exist.
