Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511338, here are decompositions:

5 + 511333 = 511338
11 + 511327 = 511338
41 + 511297 = 511338
59 + 511279 = 511338
101 + 511237 = 511338
127 + 511211 = 511338
137 + 511201 = 511338
167 + 511171 = 511338

Showing the first eight; more decompositions exist.
