Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520028, here are decompositions:

7 + 520021 = 520028
31 + 519997 = 520028
97 + 519931 = 520028
109 + 519919 = 520028
139 + 519889 = 520028
211 + 519817 = 520028
241 + 519787 = 520028
337 + 519691 = 520028

Showing the first eight; more decompositions exist.
