Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007520, here are decompositions:

23 + 1007497 = 1007520
37 + 1007483 = 1007520
53 + 1007467 = 1007520
61 + 1007459 = 1007520
79 + 1007441 = 1007520
103 + 1007417 = 1007520
139 + 1007381 = 1007520
167 + 1007353 = 1007520

Showing the first eight; more decompositions exist.
