Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105530, here are decompositions:

3 + 105527 = 105530
13 + 105517 = 105530
31 + 105499 = 105530
151 + 105379 = 105530
157 + 105373 = 105530
163 + 105367 = 105530
193 + 105337 = 105530
199 + 105331 = 105530

Showing the first eight; more decompositions exist.
