Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511490, here are decompositions:

3 + 511487 = 511490
13 + 511477 = 511490
37 + 511453 = 511490
43 + 511447 = 511490
73 + 511417 = 511490
103 + 511387 = 511490
139 + 511351 = 511490
157 + 511333 = 511490

Showing the first eight; more decompositions exist.
