Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511470, here are decompositions:

7 + 511463 = 511470
13 + 511457 = 511470
17 + 511453 = 511470
23 + 511447 = 511470
31 + 511439 = 511470
53 + 511417 = 511470
61 + 511409 = 511470
79 + 511391 = 511470

Showing the first eight; more decompositions exist.
