Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725664, here are decompositions:

7 + 8725657 = 8725664
37 + 8725627 = 8725664
43 + 8725621 = 8725664
97 + 8725567 = 8725664
307 + 8725357 = 8725664
421 + 8725243 = 8725664
457 + 8725207 = 8725664
487 + 8725177 = 8725664

Showing the first eight; more decompositions exist.
