Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511622, here are decompositions:

19 + 511603 = 511622
31 + 511591 = 511622
43 + 511579 = 511622
73 + 511549 = 511622
103 + 511519 = 511622
271 + 511351 = 511622
379 + 511243 = 511622
409 + 511213 = 511622

Showing the first eight; more decompositions exist.
