Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142996, here are decompositions:

3 + 142993 = 142996
17 + 142979 = 142996
23 + 142973 = 142996
47 + 142949 = 142996
89 + 142907 = 142996
197 + 142799 = 142996
239 + 142757 = 142996
263 + 142733 = 142996

Showing the first eight; more decompositions exist.
