Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7886, here are decompositions:

3 + 7883 = 7886
7 + 7879 = 7886
13 + 7873 = 7886
19 + 7867 = 7886
97 + 7789 = 7886
127 + 7759 = 7886
163 + 7723 = 7886
199 + 7687 = 7886

Showing the first eight; more decompositions exist.
