Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42102, here are decompositions:

13 + 42089 = 42102
19 + 42083 = 42102
29 + 42073 = 42102
31 + 42071 = 42102
41 + 42061 = 42102
59 + 42043 = 42102
79 + 42023 = 42102
83 + 42019 = 42102

Showing the first eight; more decompositions exist.
