Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725780, here are decompositions:

23 + 8725757 = 8725780
47 + 8725733 = 8725780
137 + 8725643 = 8725780
149 + 8725631 = 8725780
233 + 8725547 = 8725780
257 + 8725523 = 8725780
269 + 8725511 = 8725780
281 + 8725499 = 8725780

Showing the first eight; more decompositions exist.
