Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102002, here are decompositions:

3 + 101999 = 102002
73 + 101929 = 102002
139 + 101863 = 102002
163 + 101839 = 102002
283 + 101719 = 102002
349 + 101653 = 102002
421 + 101581 = 102002
499 + 101503 = 102002

Showing the first eight; more decompositions exist.
