Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30144, here are decompositions:

5 + 30139 = 30144
7 + 30137 = 30144
11 + 30133 = 30144
31 + 30113 = 30144
41 + 30103 = 30144
47 + 30097 = 30144
53 + 30091 = 30144
73 + 30071 = 30144

Showing the first eight; more decompositions exist.
