Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725684, here are decompositions:

3 + 8725681 = 8725684
41 + 8725643 = 8725684
53 + 8725631 = 8725684
113 + 8725571 = 8725684
137 + 8725547 = 8725684
173 + 8725511 = 8725684
263 + 8725421 = 8725684
293 + 8725391 = 8725684

Showing the first eight; more decompositions exist.
