Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581744, here are decompositions:

13 + 581731 = 581744
43 + 581701 = 581744
61 + 581683 = 581744
127 + 581617 = 581744
193 + 581551 = 581744
223 + 581521 = 581744
271 + 581473 = 581744
337 + 581407 = 581744

Showing the first eight; more decompositions exist.
