Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581876, here are decompositions:

3 + 581873 = 581876
7 + 581869 = 581876
13 + 581863 = 581876
19 + 581857 = 581876
67 + 581809 = 581876
79 + 581797 = 581876
103 + 581773 = 581876
109 + 581767 = 581876

Showing the first eight; more decompositions exist.
