Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725898, here are decompositions:

67 + 8725831 = 8725898
199 + 8725699 = 8725898
229 + 8725669 = 8725898
241 + 8725657 = 8725898
271 + 8725627 = 8725898
277 + 8725621 = 8725898
331 + 8725567 = 8725898
367 + 8725531 = 8725898

Showing the first eight; more decompositions exist.
