Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72002, here are decompositions:

3 + 71999 = 72002
19 + 71983 = 72002
31 + 71971 = 72002
61 + 71941 = 72002
103 + 71899 = 72002
181 + 71821 = 72002
193 + 71809 = 72002
241 + 71761 = 72002

Showing the first eight; more decompositions exist.
