Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545088, here are decompositions:

31 + 545057 = 545088
59 + 545029 = 545088
109 + 544979 = 545088
127 + 544961 = 545088
151 + 544937 = 545088
191 + 544897 = 545088
199 + 544889 = 545088
211 + 544877 = 545088

Showing the first eight; more decompositions exist.
