Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545450, here are decompositions:

7 + 545443 = 545450
13 + 545437 = 545450
79 + 545371 = 545450
193 + 545257 = 545450
211 + 545239 = 545450
307 + 545143 = 545450
421 + 545029 = 545450
487 + 544963 = 545450

Showing the first eight; more decompositions exist.
