Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99142, here are decompositions:

3 + 99139 = 99142
5 + 99137 = 99142
11 + 99131 = 99142
23 + 99119 = 99142
53 + 99089 = 99142
59 + 99083 = 99142
89 + 99053 = 99142
101 + 99041 = 99142

Showing the first eight; more decompositions exist.
