Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725856, here are decompositions:

43 + 8725813 = 8725856
157 + 8725699 = 8725856
199 + 8725657 = 8725856
229 + 8725627 = 8725856
367 + 8725489 = 8725856
397 + 8725459 = 8725856
457 + 8725399 = 8725856
499 + 8725357 = 8725856

Showing the first eight; more decompositions exist.
