Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105136, here are decompositions:

29 + 105107 = 105136
113 + 105023 = 105136
137 + 104999 = 105136
149 + 104987 = 105136
257 + 104879 = 105136
347 + 104789 = 105136
419 + 104717 = 105136
443 + 104693 = 105136

Showing the first eight; more decompositions exist.
