Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144732, here are decompositions:

13 + 144719 = 144732
23 + 144709 = 144732
31 + 144701 = 144732
61 + 144671 = 144732
73 + 144659 = 144732
103 + 144629 = 144732
139 + 144593 = 144732
149 + 144583 = 144732

Showing the first eight; more decompositions exist.
