Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730726, here are decompositions:

29 + 8730697 = 8730726
97 + 8730629 = 8730726
107 + 8730619 = 8730726
149 + 8730577 = 8730726
167 + 8730559 = 8730726
197 + 8730529 = 8730726
239 + 8730487 = 8730726
349 + 8730377 = 8730726

Showing the first eight; more decompositions exist.
