Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725690, here are decompositions:

47 + 8725643 = 8725690
59 + 8725631 = 8725690
167 + 8725523 = 8725690
179 + 8725511 = 8725690
191 + 8725499 = 8725690
227 + 8725463 = 8725690
269 + 8725421 = 8725690
293 + 8725397 = 8725690

Showing the first eight; more decompositions exist.
