Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30132, here are decompositions:

13 + 30119 = 30132
19 + 30113 = 30132
23 + 30109 = 30132
29 + 30103 = 30132
41 + 30091 = 30132
43 + 30089 = 30132
61 + 30071 = 30132
73 + 30059 = 30132

Showing the first eight; more decompositions exist.
