Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15132, here are decompositions:

11 + 15121 = 15132
31 + 15101 = 15132
41 + 15091 = 15132
59 + 15073 = 15132
71 + 15061 = 15132
79 + 15053 = 15132
101 + 15031 = 15132
149 + 14983 = 15132

Showing the first eight; more decompositions exist.
