Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545544, here are decompositions:

11 + 545533 = 545544
17 + 545527 = 545544
23 + 545521 = 545544
47 + 545497 = 545544
61 + 545483 = 545544
67 + 545477 = 545544
71 + 545473 = 545544
101 + 545443 = 545544

Showing the first eight; more decompositions exist.
