Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143526, here are decompositions:

7 + 143519 = 143526
13 + 143513 = 143526
17 + 143509 = 143526
23 + 143503 = 143526
37 + 143489 = 143526
43 + 143483 = 143526
59 + 143467 = 143526
83 + 143443 = 143526

Showing the first eight; more decompositions exist.
