Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051520, here are decompositions:

13 + 1051507 = 1051520
61 + 1051459 = 1051520
97 + 1051423 = 1051520
103 + 1051417 = 1051520
229 + 1051291 = 1051520
367 + 1051153 = 1051520
373 + 1051147 = 1051520
439 + 1051081 = 1051520

Showing the first eight; more decompositions exist.
