Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642726, here are decompositions:

3 + 8642723 = 8642726
193 + 8642533 = 8642726
277 + 8642449 = 8642726
397 + 8642329 = 8642726
607 + 8642119 = 8642726
619 + 8642107 = 8642726
739 + 8641987 = 8642726
769 + 8641957 = 8642726

Showing the first eight; more decompositions exist.
