Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540252, here are decompositions:

19 + 540233 = 540252
71 + 540181 = 540252
73 + 540179 = 540252
79 + 540173 = 540252
103 + 540149 = 540252
113 + 540139 = 540252
131 + 540121 = 540252
151 + 540101 = 540252

Showing the first eight; more decompositions exist.
