Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625820, here are decompositions:

11 + 8625809 = 8625820
113 + 8625707 = 8625820
131 + 8625689 = 8625820
179 + 8625641 = 8625820
233 + 8625587 = 8625820
293 + 8625527 = 8625820
311 + 8625509 = 8625820
353 + 8625467 = 8625820

Showing the first eight; more decompositions exist.
