Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144782, here are decompositions:

3 + 144779 = 144782
19 + 144763 = 144782
31 + 144751 = 144782
73 + 144709 = 144782
193 + 144589 = 144782
199 + 144583 = 144782
241 + 144541 = 144782
271 + 144511 = 144782

Showing the first eight; more decompositions exist.
