Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581594, here are decompositions:

37 + 581557 = 581594
43 + 581551 = 581594
67 + 581527 = 581594
73 + 581521 = 581594
103 + 581491 = 581594
151 + 581443 = 581594
241 + 581353 = 581594
271 + 581323 = 581594

Showing the first eight; more decompositions exist.
