Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545254, here are decompositions:

23 + 545231 = 545254
41 + 545213 = 545254
113 + 545141 = 545254
137 + 545117 = 545254
167 + 545087 = 545254
191 + 545063 = 545254
197 + 545057 = 545254
293 + 544961 = 545254

Showing the first eight; more decompositions exist.
