Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620726, here are decompositions:

3 + 8620723 = 8620726
5 + 8620721 = 8620726
53 + 8620673 = 8620726
89 + 8620637 = 8620726
137 + 8620589 = 8620726
173 + 8620553 = 8620726
197 + 8620529 = 8620726
227 + 8620499 = 8620726

Showing the first eight; more decompositions exist.
