Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86726, here are decompositions:

7 + 86719 = 86726
37 + 86689 = 86726
97 + 86629 = 86726
127 + 86599 = 86726
139 + 86587 = 86726
193 + 86533 = 86726
313 + 86413 = 86726
337 + 86389 = 86726

Showing the first eight; more decompositions exist.
