Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105506, here are decompositions:

3 + 105503 = 105506
7 + 105499 = 105506
109 + 105397 = 105506
127 + 105379 = 105506
139 + 105367 = 105506
229 + 105277 = 105506
277 + 105229 = 105506
307 + 105199 = 105506

Showing the first eight; more decompositions exist.
