Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144788, here are decompositions:

31 + 144757 = 144788
37 + 144751 = 144788
79 + 144709 = 144788
199 + 144589 = 144788
211 + 144577 = 144788
277 + 144511 = 144788
307 + 144481 = 144788
337 + 144451 = 144788

Showing the first eight; more decompositions exist.
