Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725658, here are decompositions:

31 + 8725627 = 8725658
37 + 8725621 = 8725658
127 + 8725531 = 8725658
199 + 8725459 = 8725658
229 + 8725429 = 8725658
379 + 8725279 = 8725658
439 + 8725219 = 8725658
499 + 8725159 = 8725658

Showing the first eight; more decompositions exist.
