Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581938, here are decompositions:

17 + 581921 = 581938
29 + 581909 = 581938
47 + 581891 = 581938
239 + 581699 = 581938
251 + 581687 = 581938
281 + 581657 = 581938
389 + 581549 = 581938
479 + 581459 = 581938

Showing the first eight; more decompositions exist.
