Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30126, here are decompositions:

7 + 30119 = 30126
13 + 30113 = 30126
17 + 30109 = 30126
23 + 30103 = 30126
29 + 30097 = 30126
37 + 30089 = 30126
67 + 30059 = 30126
79 + 30047 = 30126

Showing the first eight; more decompositions exist.
