Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144180, here are decompositions:

7 + 144173 = 144180
11 + 144169 = 144180
13 + 144167 = 144180
17 + 144163 = 144180
19 + 144161 = 144180
41 + 144139 = 144180
107 + 144073 = 144180
109 + 144071 = 144180

Showing the first eight; more decompositions exist.
