Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002180, here are decompositions:

7 + 1002173 = 1002180
29 + 1002151 = 1002180
31 + 1002149 = 1002180
37 + 1002143 = 1002180
59 + 1002121 = 1002180
71 + 1002109 = 1002180
79 + 1002101 = 1002180
89 + 1002091 = 1002180

Showing the first eight; more decompositions exist.
