Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545554, here are decompositions:

3 + 545551 = 545554
5 + 545549 = 545554
11 + 545543 = 545554
71 + 545483 = 545554
167 + 545387 = 545554
263 + 545291 = 545554
461 + 545093 = 545554
467 + 545087 = 545554

Showing the first eight; more decompositions exist.
