Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012520, here are decompositions:

7 + 1012513 = 1012520
13 + 1012507 = 1012520
31 + 1012489 = 1012520
73 + 1012447 = 1012520
97 + 1012423 = 1012520
109 + 1012411 = 1012520
151 + 1012369 = 1012520
199 + 1012321 = 1012520

Showing the first eight; more decompositions exist.
