Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521078, here are decompositions:

31 + 521047 = 521078
37 + 521041 = 521078
97 + 520981 = 521078
109 + 520969 = 521078
157 + 520921 = 521078
211 + 520867 = 521078
241 + 520837 = 521078
331 + 520747 = 521078

Showing the first eight; more decompositions exist.
