Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511436, here are decompositions:

19 + 511417 = 511436
103 + 511333 = 511436
109 + 511327 = 511436
139 + 511297 = 511436
157 + 511279 = 511436
193 + 511243 = 511436
199 + 511237 = 511436
223 + 511213 = 511436

Showing the first eight; more decompositions exist.
