Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156144, here are decompositions:

5 + 156139 = 156144
13 + 156131 = 156144
17 + 156127 = 156144
73 + 156071 = 156144
83 + 156061 = 156144
103 + 156041 = 156144
137 + 156007 = 156144
223 + 155921 = 156144

Showing the first eight; more decompositions exist.
