Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712726, here are decompositions:

13 + 8712713 = 8712726
17 + 8712709 = 8712726
97 + 8712629 = 8712726
149 + 8712577 = 8712726
179 + 8712547 = 8712726
193 + 8712533 = 8712726
229 + 8712497 = 8712726
353 + 8712373 = 8712726

Showing the first eight; more decompositions exist.
