Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128052, here are decompositions:

5 + 128047 = 128052
19 + 128033 = 128052
31 + 128021 = 128052
73 + 127979 = 128052
79 + 127973 = 128052
101 + 127951 = 128052
131 + 127921 = 128052
139 + 127913 = 128052

Showing the first eight; more decompositions exist.
