Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105106, here are decompositions:

83 + 105023 = 105106
107 + 104999 = 105106
173 + 104933 = 105106
227 + 104879 = 105106
257 + 104849 = 105106
317 + 104789 = 105106
347 + 104759 = 105106
383 + 104723 = 105106

Showing the first eight; more decompositions exist.
