Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627478, here are decompositions:

5 + 8627473 = 8627478
11 + 8627467 = 8627478
31 + 8627447 = 8627478
37 + 8627441 = 8627478
47 + 8627431 = 8627478
61 + 8627417 = 8627478
107 + 8627371 = 8627478
127 + 8627351 = 8627478

Showing the first eight; more decompositions exist.
