Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511310, here are decompositions:

13 + 511297 = 511310
31 + 511279 = 511310
67 + 511243 = 511310
73 + 511237 = 511310
97 + 511213 = 511310
109 + 511201 = 511310
139 + 511171 = 511310
157 + 511153 = 511310

Showing the first eight; more decompositions exist.
