Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511260, here are decompositions:

17 + 511243 = 511260
23 + 511237 = 511260
37 + 511223 = 511260
47 + 511213 = 511260
59 + 511201 = 511260
67 + 511193 = 511260
83 + 511177 = 511260
89 + 511171 = 511260

Showing the first eight; more decompositions exist.
