Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144726, here are decompositions:

7 + 144719 = 144726
17 + 144709 = 144726
59 + 144667 = 144726
67 + 144659 = 144726
97 + 144629 = 144726
137 + 144589 = 144726
149 + 144577 = 144726
157 + 144569 = 144726

Showing the first eight; more decompositions exist.
