Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144764, here are decompositions:

7 + 144757 = 144764
13 + 144751 = 144764
97 + 144667 = 144764
181 + 144583 = 144764
223 + 144541 = 144764
283 + 144481 = 144764
313 + 144451 = 144764
337 + 144427 = 144764

Showing the first eight; more decompositions exist.
