Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545274, here are decompositions:

7 + 545267 = 545274
17 + 545257 = 545274
43 + 545231 = 545274
61 + 545213 = 545274
71 + 545203 = 545274
113 + 545161 = 545274
131 + 545143 = 545274
157 + 545117 = 545274

Showing the first eight; more decompositions exist.
