Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581996, here are decompositions:

13 + 581983 = 581996
43 + 581953 = 581996
127 + 581869 = 581996
139 + 581857 = 581996
199 + 581797 = 581996
223 + 581773 = 581996
229 + 581767 = 581996
313 + 581683 = 581996

Showing the first eight; more decompositions exist.
