Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545164, here are decompositions:

3 + 545161 = 545164
23 + 545141 = 545164
47 + 545117 = 545164
71 + 545093 = 545164
101 + 545063 = 545164
107 + 545057 = 545164
131 + 545033 = 545164
227 + 544937 = 545164

Showing the first eight; more decompositions exist.
