Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511442, here are decompositions:

3 + 511439 = 511442
109 + 511333 = 511442
163 + 511279 = 511442
181 + 511261 = 511442
199 + 511243 = 511442
229 + 511213 = 511442
241 + 511201 = 511442
271 + 511171 = 511442

Showing the first eight; more decompositions exist.
