Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511450, here are decompositions:

3 + 511447 = 511450
11 + 511439 = 511450
41 + 511409 = 511450
59 + 511391 = 511450
89 + 511361 = 511450
113 + 511337 = 511450
227 + 511223 = 511450
239 + 511211 = 511450

Showing the first eight; more decompositions exist.
