Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144564, here are decompositions:

23 + 144541 = 144564
53 + 144511 = 144564
67 + 144497 = 144564
83 + 144481 = 144564
103 + 144461 = 144564
113 + 144451 = 144564
137 + 144427 = 144564
151 + 144413 = 144564

Showing the first eight; more decompositions exist.
