Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143574, here are decompositions:

5 + 143569 = 143574
7 + 143567 = 143574
23 + 143551 = 143574
37 + 143537 = 143574
47 + 143527 = 143574
61 + 143513 = 143574
71 + 143503 = 143574
73 + 143501 = 143574

Showing the first eight; more decompositions exist.
