Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7910, here are decompositions:

3 + 7907 = 7910
31 + 7879 = 7910
37 + 7873 = 7910
43 + 7867 = 7910
151 + 7759 = 7910
157 + 7753 = 7910
193 + 7717 = 7910
211 + 7699 = 7910

Showing the first eight; more decompositions exist.
