Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144660, here are decompositions:

31 + 144629 = 144660
67 + 144593 = 144660
71 + 144589 = 144660
83 + 144577 = 144660
97 + 144563 = 144660
149 + 144511 = 144660
163 + 144497 = 144660
179 + 144481 = 144660

Showing the first eight; more decompositions exist.
