Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545118, here are decompositions:

29 + 545089 = 545118
31 + 545087 = 545118
61 + 545057 = 545118
89 + 545029 = 545118
139 + 544979 = 545118
157 + 544961 = 545118
181 + 544937 = 545118
191 + 544927 = 545118

Showing the first eight; more decompositions exist.
