Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7802, here are decompositions:

13 + 7789 = 7802
43 + 7759 = 7802
61 + 7741 = 7802
79 + 7723 = 7802
103 + 7699 = 7802
163 + 7639 = 7802
181 + 7621 = 7802
199 + 7603 = 7802

Showing the first eight; more decompositions exist.
