Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511356, here are decompositions:

5 + 511351 = 511356
19 + 511337 = 511356
23 + 511333 = 511356
29 + 511327 = 511356
59 + 511297 = 511356
67 + 511289 = 511356
113 + 511243 = 511356
163 + 511193 = 511356

Showing the first eight; more decompositions exist.
