Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581274, here are decompositions:

11 + 581263 = 581274
13 + 581261 = 581274
37 + 581237 = 581274
47 + 581227 = 581274
73 + 581201 = 581274
97 + 581177 = 581274
101 + 581173 = 581274
103 + 581171 = 581274

Showing the first eight; more decompositions exist.
