Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581706, here are decompositions:

5 + 581701 = 581706
7 + 581699 = 581706
19 + 581687 = 581706
23 + 581683 = 581706
43 + 581663 = 581706
67 + 581639 = 581706
89 + 581617 = 581706
107 + 581599 = 581706

Showing the first eight; more decompositions exist.
