Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545370, here are decompositions:

41 + 545329 = 545370
79 + 545291 = 545370
103 + 545267 = 545370
113 + 545257 = 545370
131 + 545239 = 545370
139 + 545231 = 545370
157 + 545213 = 545370
167 + 545203 = 545370

Showing the first eight; more decompositions exist.
