Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540208, here are decompositions:

5 + 540203 = 540208
29 + 540179 = 540208
41 + 540167 = 540208
59 + 540149 = 540208
89 + 540119 = 540208
107 + 540101 = 540208
167 + 540041 = 540208
311 + 539897 = 540208

Showing the first eight; more decompositions exist.
