Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524540, here are decompositions:

19 + 524521 = 524540
31 + 524509 = 524540
43 + 524497 = 524540
127 + 524413 = 524540
151 + 524389 = 524540
193 + 524347 = 524540
199 + 524341 = 524540
271 + 524269 = 524540

Showing the first eight; more decompositions exist.
