Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725556, here are decompositions:

67 + 8725489 = 8725556
97 + 8725459 = 8725556
127 + 8725429 = 8725556
157 + 8725399 = 8725556
193 + 8725363 = 8725556
199 + 8725357 = 8725556
277 + 8725279 = 8725556
313 + 8725243 = 8725556

Showing the first eight; more decompositions exist.
