Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105512, here are decompositions:

3 + 105509 = 105512
13 + 105499 = 105512
139 + 105373 = 105512
151 + 105361 = 105512
181 + 105331 = 105512
193 + 105319 = 105512
283 + 105229 = 105512
313 + 105199 = 105512

Showing the first eight; more decompositions exist.
