Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143556, here are decompositions:

5 + 143551 = 143556
19 + 143537 = 143556
29 + 143527 = 143556
37 + 143519 = 143556
43 + 143513 = 143556
47 + 143509 = 143556
53 + 143503 = 143556
67 + 143489 = 143556

Showing the first eight; more decompositions exist.
