Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581054, here are decompositions:

7 + 581047 = 581054
13 + 581041 = 581054
73 + 580981 = 581054
127 + 580927 = 581054
163 + 580891 = 581054
211 + 580843 = 581054
241 + 580813 = 581054
307 + 580747 = 581054

Showing the first eight; more decompositions exist.
