Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545550, here are decompositions:

7 + 545543 = 545550
17 + 545533 = 545550
23 + 545527 = 545550
29 + 545521 = 545550
53 + 545497 = 545550
67 + 545483 = 545550
73 + 545477 = 545550
101 + 545449 = 545550

Showing the first eight; more decompositions exist.
