Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144162, here are decompositions:

23 + 144139 = 144162
59 + 144103 = 144162
89 + 144073 = 144162
101 + 144061 = 144162
131 + 144031 = 144162
149 + 144013 = 144162
163 + 143999 = 144162
181 + 143981 = 144162

Showing the first eight; more decompositions exist.
