Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545008, here are decompositions:

29 + 544979 = 545008
47 + 544961 = 545008
71 + 544937 = 545008
89 + 544919 = 545008
131 + 544877 = 545008
227 + 544781 = 545008
251 + 544757 = 545008
281 + 544727 = 545008

Showing the first eight; more decompositions exist.
