Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540286, here are decompositions:

3 + 540283 = 540286
17 + 540269 = 540286
53 + 540233 = 540286
83 + 540203 = 540286
107 + 540179 = 540286
113 + 540173 = 540286
137 + 540149 = 540286
167 + 540119 = 540286

Showing the first eight; more decompositions exist.
