Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511222, here are decompositions:

11 + 511211 = 511222
29 + 511193 = 511222
53 + 511169 = 511222
59 + 511163 = 511222
71 + 511151 = 511222
113 + 511109 = 511222
233 + 510989 = 511222
281 + 510941 = 511222

Showing the first eight; more decompositions exist.
