Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144548, here are decompositions:

7 + 144541 = 144548
37 + 144511 = 144548
67 + 144481 = 144548
97 + 144451 = 144548
109 + 144439 = 144548
139 + 144409 = 144548
199 + 144349 = 144548
241 + 144307 = 144548

Showing the first eight; more decompositions exist.
