Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581948, here are decompositions:

7 + 581941 = 581948
79 + 581869 = 581948
127 + 581821 = 581948
139 + 581809 = 581948
151 + 581797 = 581948
181 + 581767 = 581948
331 + 581617 = 581948
349 + 581599 = 581948

Showing the first eight; more decompositions exist.
