Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30242, here are decompositions:

19 + 30223 = 30242
31 + 30211 = 30242
61 + 30181 = 30242
73 + 30169 = 30242
103 + 30139 = 30242
109 + 30133 = 30242
139 + 30103 = 30242
151 + 30091 = 30242

Showing the first eight; more decompositions exist.
