Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99138, here are decompositions:

5 + 99133 = 99138
7 + 99131 = 99138
19 + 99119 = 99138
29 + 99109 = 99138
59 + 99079 = 99138
97 + 99041 = 99138
139 + 98999 = 99138
157 + 98981 = 99138

Showing the first eight; more decompositions exist.
