Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725812, here are decompositions:

13 + 8725799 = 8725812
79 + 8725733 = 8725812
113 + 8725699 = 8725812
131 + 8725681 = 8725812
181 + 8725631 = 8725812
191 + 8725621 = 8725812
241 + 8725571 = 8725812
281 + 8725531 = 8725812

Showing the first eight; more decompositions exist.
