Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725928, here are decompositions:

97 + 8725831 = 8725928
229 + 8725699 = 8725928
271 + 8725657 = 8725928
307 + 8725621 = 8725928
397 + 8725531 = 8725928
439 + 8725489 = 8725928
499 + 8725429 = 8725928
571 + 8725357 = 8725928

Showing the first eight; more decompositions exist.
