Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625580, here are decompositions:

53 + 8625527 = 8625580
59 + 8625521 = 8625580
71 + 8625509 = 8625580
101 + 8625479 = 8625580
113 + 8625467 = 8625580
149 + 8625431 = 8625580
263 + 8625317 = 8625580
269 + 8625311 = 8625580

Showing the first eight; more decompositions exist.
