Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7946, here are decompositions:

13 + 7933 = 7946
19 + 7927 = 7946
67 + 7879 = 7946
73 + 7873 = 7946
79 + 7867 = 7946
157 + 7789 = 7946
193 + 7753 = 7946
223 + 7723 = 7946

Showing the first eight; more decompositions exist.
