Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017520, here are decompositions:

41 + 1017479 = 1017520
47 + 1017473 = 1017520
71 + 1017449 = 1017520
83 + 1017437 = 1017520
137 + 1017383 = 1017520
149 + 1017371 = 1017520
167 + 1017353 = 1017520
173 + 1017347 = 1017520

Showing the first eight; more decompositions exist.
