Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511460, here are decompositions:

3 + 511457 = 511460
7 + 511453 = 511460
13 + 511447 = 511460
43 + 511417 = 511460
73 + 511387 = 511460
109 + 511351 = 511460
127 + 511333 = 511460
163 + 511297 = 511460

Showing the first eight; more decompositions exist.
