Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80002, here are decompositions:

3 + 79999 = 80002
5 + 79997 = 80002
23 + 79979 = 80002
29 + 79973 = 80002
59 + 79943 = 80002
101 + 79901 = 80002
113 + 79889 = 80002
173 + 79829 = 80002

Showing the first eight; more decompositions exist.
