Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725912, here are decompositions:

71 + 8725841 = 8725912
89 + 8725823 = 8725912
113 + 8725799 = 8725912
179 + 8725733 = 8725912
269 + 8725643 = 8725912
281 + 8725631 = 8725912
389 + 8725523 = 8725912
401 + 8725511 = 8725912

Showing the first eight; more decompositions exist.
