Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545404, here are decompositions:

17 + 545387 = 545404
113 + 545291 = 545404
137 + 545267 = 545404
173 + 545231 = 545404
191 + 545213 = 545404
263 + 545141 = 545404
311 + 545093 = 545404
317 + 545087 = 545404

Showing the first eight; more decompositions exist.
