Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144402, here are decompositions:

19 + 144383 = 144402
23 + 144379 = 144402
53 + 144349 = 144402
61 + 144341 = 144402
79 + 144323 = 144402
103 + 144299 = 144402
113 + 144289 = 144402
131 + 144271 = 144402

Showing the first eight; more decompositions exist.
