Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152912, here are decompositions:

3 + 152909 = 152912
13 + 152899 = 152912
61 + 152851 = 152912
73 + 152839 = 152912
79 + 152833 = 152912
103 + 152809 = 152912
241 + 152671 = 152912
271 + 152641 = 152912

Showing the first eight; more decompositions exist.
