Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102726, here are decompositions:

47 + 102679 = 102726
53 + 102673 = 102726
59 + 102667 = 102726
73 + 102653 = 102726
79 + 102647 = 102726
83 + 102643 = 102726
139 + 102587 = 102726
163 + 102563 = 102726

Showing the first eight; more decompositions exist.
