Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545226, here are decompositions:

13 + 545213 = 545226
23 + 545203 = 545226
37 + 545189 = 545226
83 + 545143 = 545226
109 + 545117 = 545226
137 + 545089 = 545226
139 + 545087 = 545226
163 + 545063 = 545226

Showing the first eight; more decompositions exist.
