Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2834, here are decompositions:

31 + 2803 = 2834
37 + 2797 = 2834
43 + 2791 = 2834
67 + 2767 = 2834
103 + 2731 = 2834
127 + 2707 = 2834
151 + 2683 = 2834
157 + 2677 = 2834

Showing the first eight; more decompositions exist.
