Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739726, here are decompositions:

5 + 8739721 = 8739726
13 + 8739713 = 8739726
53 + 8739673 = 8739726
59 + 8739667 = 8739726
89 + 8739637 = 8739726
103 + 8739623 = 8739726
109 + 8739617 = 8739726
197 + 8739529 = 8739726

Showing the first eight; more decompositions exist.
