Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545446, here are decompositions:

3 + 545443 = 545446
17 + 545429 = 545446
59 + 545387 = 545446
179 + 545267 = 545446
233 + 545213 = 545446
257 + 545189 = 545446
353 + 545093 = 545446
359 + 545087 = 545446

Showing the first eight; more decompositions exist.
