Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30002, here are decompositions:

13 + 29989 = 30002
19 + 29983 = 30002
43 + 29959 = 30002
139 + 29863 = 30002
151 + 29851 = 30002
199 + 29803 = 30002
241 + 29761 = 30002
331 + 29671 = 30002

Showing the first eight; more decompositions exist.
