Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511290, here are decompositions:

11 + 511279 = 511290
29 + 511261 = 511290
47 + 511243 = 511290
53 + 511237 = 511290
67 + 511223 = 511290
79 + 511211 = 511290
89 + 511201 = 511290
97 + 511193 = 511290

Showing the first eight; more decompositions exist.
