Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581976, here are decompositions:

23 + 581953 = 581976
29 + 581947 = 581976
67 + 581909 = 581976
103 + 581873 = 581976
107 + 581869 = 581976
113 + 581863 = 581976
167 + 581809 = 581976
179 + 581797 = 581976

Showing the first eight; more decompositions exist.
