Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545136, here are decompositions:

5 + 545131 = 545136
19 + 545117 = 545136
43 + 545093 = 545136
47 + 545089 = 545136
73 + 545063 = 545136
79 + 545057 = 545136
103 + 545033 = 545136
107 + 545029 = 545136

Showing the first eight; more decompositions exist.
