Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625538, here are decompositions:

11 + 8625527 = 8625538
17 + 8625521 = 8625538
29 + 8625509 = 8625538
59 + 8625479 = 8625538
71 + 8625467 = 8625538
107 + 8625431 = 8625538
179 + 8625359 = 8625538
227 + 8625311 = 8625538

Showing the first eight; more decompositions exist.
