Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581852, here are decompositions:

31 + 581821 = 581852
43 + 581809 = 581852
79 + 581773 = 581852
109 + 581743 = 581852
151 + 581701 = 581852
331 + 581521 = 581852
379 + 581473 = 581852
409 + 581443 = 581852

Showing the first eight; more decompositions exist.
