Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725826, here are decompositions:

3 + 8725823 = 8725826
13 + 8725813 = 8725826
127 + 8725699 = 8725826
157 + 8725669 = 8725826
199 + 8725627 = 8725826
337 + 8725489 = 8725826
367 + 8725459 = 8725826
397 + 8725429 = 8725826

Showing the first eight; more decompositions exist.
