Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30206, here are decompositions:

3 + 30203 = 30206
19 + 30187 = 30206
37 + 30169 = 30206
67 + 30139 = 30206
73 + 30133 = 30206
97 + 30109 = 30206
103 + 30103 = 30206
109 + 30097 = 30206

Showing the first eight; more decompositions exist.
