Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048520, here are decompositions:

3 + 1048517 = 1048520
13 + 1048507 = 1048520
73 + 1048447 = 1048520
97 + 1048423 = 1048520
163 + 1048357 = 1048520
211 + 1048309 = 1048520
229 + 1048291 = 1048520
307 + 1048213 = 1048520

Showing the first eight; more decompositions exist.
