Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145002, here are decompositions:

19 + 144983 = 145002
29 + 144973 = 145002
41 + 144961 = 145002
61 + 144941 = 145002
71 + 144931 = 145002
103 + 144899 = 145002
113 + 144889 = 145002
163 + 144839 = 145002

Showing the first eight; more decompositions exist.
