Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144156, here are decompositions:

17 + 144139 = 144156
53 + 144103 = 144156
83 + 144073 = 144156
157 + 143999 = 144156
179 + 143977 = 144156
277 + 143879 = 144156
283 + 143873 = 144156
349 + 143807 = 144156

Showing the first eight; more decompositions exist.
