Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7904, here are decompositions:

3 + 7901 = 7904
31 + 7873 = 7904
37 + 7867 = 7904
151 + 7753 = 7904
163 + 7741 = 7904
181 + 7723 = 7904
223 + 7681 = 7904
283 + 7621 = 7904

Showing the first eight; more decompositions exist.
