Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20102, here are decompositions:

13 + 20089 = 20102
31 + 20071 = 20102
73 + 20029 = 20102
79 + 20023 = 20102
109 + 19993 = 20102
139 + 19963 = 20102
211 + 19891 = 20102
241 + 19861 = 20102

Showing the first eight; more decompositions exist.
