Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144342, here are decompositions:

19 + 144323 = 144342
31 + 144311 = 144342
43 + 144299 = 144342
53 + 144289 = 144342
71 + 144271 = 144342
83 + 144259 = 144342
89 + 144253 = 144342
101 + 144241 = 144342

Showing the first eight; more decompositions exist.
