Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581798, here are decompositions:

31 + 581767 = 581798
67 + 581731 = 581798
97 + 581701 = 581798
181 + 581617 = 581798
199 + 581599 = 581798
241 + 581557 = 581798
271 + 581527 = 581798
277 + 581521 = 581798

Showing the first eight; more decompositions exist.
