Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725562, here are decompositions:

31 + 8725531 = 8725562
73 + 8725489 = 8725562
103 + 8725459 = 8725562
163 + 8725399 = 8725562
199 + 8725363 = 8725562
283 + 8725279 = 8725562
379 + 8725183 = 8725562
409 + 8725153 = 8725562

Showing the first eight; more decompositions exist.
