Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8002, here are decompositions:

53 + 7949 = 8002
83 + 7919 = 8002
101 + 7901 = 8002
149 + 7853 = 8002
173 + 7829 = 8002
179 + 7823 = 8002
311 + 7691 = 8002
353 + 7649 = 8002

Showing the first eight; more decompositions exist.
