Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153504, here are decompositions:

5 + 153499 = 153504
17 + 153487 = 153504
47 + 153457 = 153504
61 + 153443 = 153504
67 + 153437 = 153504
83 + 153421 = 153504
97 + 153407 = 153504
151 + 153353 = 153504

Showing the first eight; more decompositions exist.
