Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144378, here are decompositions:

29 + 144349 = 144378
37 + 144341 = 144378
67 + 144311 = 144378
71 + 144307 = 144378
79 + 144299 = 144378
89 + 144289 = 144378
107 + 144271 = 144378
131 + 144247 = 144378

Showing the first eight; more decompositions exist.
