Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511420, here are decompositions:

3 + 511417 = 511420
11 + 511409 = 511420
29 + 511391 = 511420
59 + 511361 = 511420
83 + 511337 = 511420
131 + 511289 = 511420
197 + 511223 = 511420
227 + 511193 = 511420

Showing the first eight; more decompositions exist.
