Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511708, here are decompositions:

5 + 511703 = 511708
17 + 511691 = 511708
149 + 511559 = 511708
167 + 511541 = 511708
251 + 511457 = 511708
269 + 511439 = 511708
317 + 511391 = 511708
347 + 511361 = 511708

Showing the first eight; more decompositions exist.
