Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143472, here are decompositions:

5 + 143467 = 143472
11 + 143461 = 143472
29 + 143443 = 143472
53 + 143419 = 143472
59 + 143413 = 143472
71 + 143401 = 143472
139 + 143333 = 143472
181 + 143291 = 143472

Showing the first eight; more decompositions exist.
