Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545242, here are decompositions:

3 + 545239 = 545242
11 + 545231 = 545242
29 + 545213 = 545242
53 + 545189 = 545242
101 + 545141 = 545242
149 + 545093 = 545242
179 + 545063 = 545242
263 + 544979 = 545242

Showing the first eight; more decompositions exist.
