Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512440, here are decompositions:

11 + 512429 = 512440
107 + 512333 = 512440
191 + 512249 = 512440
233 + 512207 = 512440
293 + 512147 = 512440
347 + 512093 = 512440
419 + 512021 = 512440
431 + 512009 = 512440

Showing the first eight; more decompositions exist.
