Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180726, here are decompositions:

47 + 180679 = 180726
59 + 180667 = 180726
79 + 180647 = 180726
97 + 180629 = 180726
103 + 180623 = 180726
109 + 180617 = 180726
157 + 180569 = 180726
163 + 180563 = 180726

Showing the first eight; more decompositions exist.
