Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627540, here are decompositions:

7 + 8627533 = 8627540
13 + 8627527 = 8627540
37 + 8627503 = 8627540
43 + 8627497 = 8627540
67 + 8627473 = 8627540
73 + 8627467 = 8627540
109 + 8627431 = 8627540
199 + 8627341 = 8627540

Showing the first eight; more decompositions exist.
