Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581598, here are decompositions:

41 + 581557 = 581598
47 + 581551 = 581598
71 + 581527 = 581598
107 + 581491 = 581598
139 + 581459 = 581598
151 + 581447 = 581598
191 + 581407 = 581598
229 + 581369 = 581598

Showing the first eight; more decompositions exist.
