Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545142, here are decompositions:

11 + 545131 = 545142
53 + 545089 = 545142
79 + 545063 = 545142
109 + 545033 = 545142
113 + 545029 = 545142
163 + 544979 = 545142
179 + 544963 = 545142
181 + 544961 = 545142

Showing the first eight; more decompositions exist.
