Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511650, here are decompositions:

17 + 511633 = 511650
19 + 511631 = 511650
23 + 511627 = 511650
47 + 511603 = 511650
59 + 511591 = 511650
67 + 511583 = 511650
71 + 511579 = 511650
101 + 511549 = 511650

Showing the first eight; more decompositions exist.
