Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7902, here are decompositions:

19 + 7883 = 7902
23 + 7879 = 7902
29 + 7873 = 7902
61 + 7841 = 7902
73 + 7829 = 7902
79 + 7823 = 7902
109 + 7793 = 7902
113 + 7789 = 7902

Showing the first eight; more decompositions exist.
