Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545540, here are decompositions:

7 + 545533 = 545540
13 + 545527 = 545540
19 + 545521 = 545540
43 + 545497 = 545540
67 + 545473 = 545540
97 + 545443 = 545540
103 + 545437 = 545540
211 + 545329 = 545540

Showing the first eight; more decompositions exist.
