Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144318, here are decompositions:

7 + 144311 = 144318
11 + 144307 = 144318
19 + 144299 = 144318
29 + 144289 = 144318
47 + 144271 = 144318
59 + 144259 = 144318
71 + 144247 = 144318
149 + 144169 = 144318

Showing the first eight; more decompositions exist.
