Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142580, here are decompositions:

7 + 142573 = 142580
13 + 142567 = 142580
37 + 142543 = 142580
43 + 142537 = 142580
79 + 142501 = 142580
127 + 142453 = 142580
199 + 142381 = 142580
211 + 142369 = 142580

Showing the first eight; more decompositions exist.
