Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30182, here are decompositions:

13 + 30169 = 30182
43 + 30139 = 30182
73 + 30109 = 30182
79 + 30103 = 30182
193 + 29989 = 30182
199 + 29983 = 30182
223 + 29959 = 30182
331 + 29851 = 30182

Showing the first eight; more decompositions exist.
