Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511380, here are decompositions:

19 + 511361 = 511380
29 + 511351 = 511380
43 + 511337 = 511380
47 + 511333 = 511380
53 + 511327 = 511380
83 + 511297 = 511380
101 + 511279 = 511380
137 + 511243 = 511380

Showing the first eight; more decompositions exist.
