Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100158, here are decompositions:

5 + 100153 = 100158
7 + 100151 = 100158
29 + 100129 = 100158
89 + 100069 = 100158
101 + 100057 = 100158
109 + 100049 = 100158
139 + 100019 = 100158
167 + 99991 = 100158

Showing the first eight; more decompositions exist.
