Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545320, here are decompositions:

29 + 545291 = 545320
53 + 545267 = 545320
89 + 545231 = 545320
107 + 545213 = 545320
131 + 545189 = 545320
179 + 545141 = 545320
227 + 545093 = 545320
233 + 545087 = 545320

Showing the first eight; more decompositions exist.
