Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1061520, here are decompositions:

7 + 1061513 = 1061520
11 + 1061509 = 1061520
37 + 1061483 = 1061520
67 + 1061453 = 1061520
79 + 1061441 = 1061520
107 + 1061413 = 1061520
113 + 1061407 = 1061520
127 + 1061393 = 1061520

Showing the first eight; more decompositions exist.
