Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144270, here are decompositions:

11 + 144259 = 144270
17 + 144253 = 144270
23 + 144247 = 144270
29 + 144241 = 144270
47 + 144223 = 144270
67 + 144203 = 144270
97 + 144173 = 144270
101 + 144169 = 144270

Showing the first eight; more decompositions exist.
