Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720726, here are decompositions:

13 + 8720713 = 8720726
19 + 8720707 = 8720726
37 + 8720689 = 8720726
97 + 8720629 = 8720726
103 + 8720623 = 8720726
109 + 8720617 = 8720726
193 + 8720533 = 8720726
229 + 8720497 = 8720726

Showing the first eight; more decompositions exist.
