Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627580, here are decompositions:

7 + 8627573 = 8627580
11 + 8627569 = 8627580
19 + 8627561 = 8627580
47 + 8627533 = 8627580
53 + 8627527 = 8627580
67 + 8627513 = 8627580
83 + 8627497 = 8627580
107 + 8627473 = 8627580

Showing the first eight; more decompositions exist.
