Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545004, here are decompositions:

41 + 544963 = 545004
43 + 544961 = 545004
67 + 544937 = 545004
101 + 544903 = 545004
107 + 544897 = 545004
127 + 544877 = 545004
167 + 544837 = 545004
191 + 544813 = 545004

Showing the first eight; more decompositions exist.
