Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143544, here are decompositions:

7 + 143537 = 143544
17 + 143527 = 143544
31 + 143513 = 143544
41 + 143503 = 143544
43 + 143501 = 143544
61 + 143483 = 143544
67 + 143477 = 143544
83 + 143461 = 143544

Showing the first eight; more decompositions exist.
