Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511452, here are decompositions:

5 + 511447 = 511452
13 + 511439 = 511452
43 + 511409 = 511452
61 + 511391 = 511452
101 + 511351 = 511452
163 + 511289 = 511452
173 + 511279 = 511452
191 + 511261 = 511452

Showing the first eight; more decompositions exist.
