Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30150, here are decompositions:

11 + 30139 = 30150
13 + 30137 = 30150
17 + 30133 = 30150
31 + 30119 = 30150
37 + 30113 = 30150
41 + 30109 = 30150
47 + 30103 = 30150
53 + 30097 = 30150

Showing the first eight; more decompositions exist.
