Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511626, here are decompositions:

23 + 511603 = 511626
43 + 511583 = 511626
47 + 511579 = 511626
53 + 511573 = 511626
67 + 511559 = 511626
103 + 511523 = 511626
107 + 511519 = 511626
139 + 511487 = 511626

Showing the first eight; more decompositions exist.
