Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143580, here are decompositions:

7 + 143573 = 143580
11 + 143569 = 143580
13 + 143567 = 143580
29 + 143551 = 143580
43 + 143537 = 143580
53 + 143527 = 143580
61 + 143519 = 143580
67 + 143513 = 143580

Showing the first eight; more decompositions exist.
