Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624520, here are decompositions:

13 + 8624507 = 8624520
17 + 8624503 = 8624520
43 + 8624477 = 8624520
61 + 8624459 = 8624520
71 + 8624449 = 8624520
127 + 8624393 = 8624520
137 + 8624383 = 8624520
167 + 8624353 = 8624520

Showing the first eight; more decompositions exist.
