Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2810, here are decompositions:

7 + 2803 = 2810
13 + 2797 = 2810
19 + 2791 = 2810
43 + 2767 = 2810
61 + 2749 = 2810
79 + 2731 = 2810
97 + 2713 = 2810
103 + 2707 = 2810

Showing the first eight; more decompositions exist.
