Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545344, here are decompositions:

53 + 545291 = 545344
113 + 545231 = 545344
131 + 545213 = 545344
227 + 545117 = 545344
251 + 545093 = 545344
257 + 545087 = 545344
281 + 545063 = 545344
311 + 545033 = 545344

Showing the first eight; more decompositions exist.
