Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142992, here are decompositions:

11 + 142981 = 142992
13 + 142979 = 142992
19 + 142973 = 142992
23 + 142969 = 142992
29 + 142963 = 142992
43 + 142949 = 142992
53 + 142939 = 142992
89 + 142903 = 142992

Showing the first eight; more decompositions exist.
