Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627538, here are decompositions:

5 + 8627533 = 8627538
11 + 8627527 = 8627538
41 + 8627497 = 8627538
71 + 8627467 = 8627538
97 + 8627441 = 8627538
107 + 8627431 = 8627538
109 + 8627429 = 8627538
167 + 8627371 = 8627538

Showing the first eight; more decompositions exist.
