Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152040, here are decompositions:

11 + 152029 = 152040
13 + 152027 = 152040
23 + 152017 = 152040
37 + 152003 = 152040
71 + 151969 = 152040
73 + 151967 = 152040
101 + 151939 = 152040
103 + 151937 = 152040

Showing the first eight; more decompositions exist.
