Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40002, here are decompositions:

13 + 39989 = 40002
19 + 39983 = 40002
23 + 39979 = 40002
31 + 39971 = 40002
73 + 39929 = 40002
101 + 39901 = 40002
139 + 39863 = 40002
163 + 39839 = 40002

Showing the first eight; more decompositions exist.
