Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15726, here are decompositions:

43 + 15683 = 15726
47 + 15679 = 15726
59 + 15667 = 15726
79 + 15647 = 15726
83 + 15643 = 15726
97 + 15629 = 15726
107 + 15619 = 15726
157 + 15569 = 15726

Showing the first eight; more decompositions exist.
