Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152904, here are decompositions:

5 + 152899 = 152904
7 + 152897 = 152904
47 + 152857 = 152904
53 + 152851 = 152904
61 + 152843 = 152904
67 + 152837 = 152904
71 + 152833 = 152904
83 + 152821 = 152904

Showing the first eight; more decompositions exist.
