Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725894, here are decompositions:

17 + 8725877 = 8725894
53 + 8725841 = 8725894
71 + 8725823 = 8725894
137 + 8725757 = 8725894
251 + 8725643 = 8725894
263 + 8725631 = 8725894
347 + 8725547 = 8725894
383 + 8725511 = 8725894

Showing the first eight; more decompositions exist.
