Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142576, here are decompositions:

3 + 142573 = 142576
17 + 142559 = 142576
23 + 142553 = 142576
29 + 142547 = 142576
47 + 142529 = 142576
107 + 142469 = 142576
149 + 142427 = 142576
173 + 142403 = 142576

Showing the first eight; more decompositions exist.
