Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142998, here are decompositions:

5 + 142993 = 142998
17 + 142981 = 142998
19 + 142979 = 142998
29 + 142969 = 142998
59 + 142939 = 142998
101 + 142897 = 142998
127 + 142871 = 142998
131 + 142867 = 142998

Showing the first eight; more decompositions exist.
