Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511320, here are decompositions:

23 + 511297 = 511320
31 + 511289 = 511320
41 + 511279 = 511320
59 + 511261 = 511320
83 + 511237 = 511320
97 + 511223 = 511320
107 + 511213 = 511320
109 + 511211 = 511320

Showing the first eight; more decompositions exist.
