Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42130, here are decompositions:

29 + 42101 = 42130
41 + 42089 = 42130
47 + 42083 = 42130
59 + 42071 = 42130
107 + 42023 = 42130
113 + 42017 = 42130
131 + 41999 = 42130
149 + 41981 = 42130

Showing the first eight; more decompositions exist.
