Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2920, here are decompositions:

3 + 2917 = 2920
11 + 2909 = 2920
17 + 2903 = 2920
23 + 2897 = 2920
41 + 2879 = 2920
59 + 2861 = 2920
83 + 2837 = 2920
101 + 2819 = 2920

Showing the first eight; more decompositions exist.
