Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725580, here are decompositions:

13 + 8725567 = 8725580
151 + 8725429 = 8725580
181 + 8725399 = 8725580
223 + 8725357 = 8725580
337 + 8725243 = 8725580
373 + 8725207 = 8725580
397 + 8725183 = 8725580
421 + 8725159 = 8725580

Showing the first eight; more decompositions exist.
