Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144260, here are decompositions:

7 + 144253 = 144260
13 + 144247 = 144260
19 + 144241 = 144260
37 + 144223 = 144260
97 + 144163 = 144260
157 + 144103 = 144260
199 + 144061 = 144260
223 + 144037 = 144260

Showing the first eight; more decompositions exist.
