Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581276, here are decompositions:

13 + 581263 = 581276
37 + 581239 = 581276
79 + 581197 = 581276
103 + 581173 = 581276
127 + 581149 = 581276
139 + 581137 = 581276
229 + 581047 = 581276
307 + 580969 = 581276

Showing the first eight; more decompositions exist.
