Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540138, here are decompositions:

17 + 540121 = 540138
19 + 540119 = 540138
37 + 540101 = 540138
59 + 540079 = 540138
97 + 540041 = 540138
191 + 539947 = 540138
239 + 539899 = 540138
241 + 539897 = 540138

Showing the first eight; more decompositions exist.
