Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540198, here are decompositions:

11 + 540187 = 540198
17 + 540181 = 540198
19 + 540179 = 540198
31 + 540167 = 540198
41 + 540157 = 540198
59 + 540139 = 540198
79 + 540119 = 540198
97 + 540101 = 540198

Showing the first eight; more decompositions exist.
