Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545478, here are decompositions:

5 + 545473 = 545478
29 + 545449 = 545478
41 + 545437 = 545478
107 + 545371 = 545478
149 + 545329 = 545478
211 + 545267 = 545478
239 + 545239 = 545478
317 + 545161 = 545478

Showing the first eight; more decompositions exist.
