Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105192, here are decompositions:

19 + 105173 = 105192
173 + 105019 = 105192
193 + 104999 = 105192
233 + 104959 = 105192
239 + 104953 = 105192
281 + 104911 = 105192
313 + 104879 = 105192
389 + 104803 = 105192

Showing the first eight; more decompositions exist.
