Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725624, here are decompositions:

3 + 8725621 = 8725624
53 + 8725571 = 8725624
101 + 8725523 = 8725624
113 + 8725511 = 8725624
227 + 8725397 = 8725624
233 + 8725391 = 8725624
263 + 8725361 = 8725624
317 + 8725307 = 8725624

Showing the first eight; more decompositions exist.
