Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540524, here are decompositions:

7 + 540517 = 540524
13 + 540511 = 540524
151 + 540373 = 540524
157 + 540367 = 540524
181 + 540343 = 540524
223 + 540301 = 540524
241 + 540283 = 540524
307 + 540217 = 540524

Showing the first eight; more decompositions exist.
