Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105212, here are decompositions:

13 + 105199 = 105212
181 + 105031 = 105212
193 + 105019 = 105212
241 + 104971 = 105212
409 + 104803 = 105212
433 + 104779 = 105212
439 + 104773 = 105212
619 + 104593 = 105212

Showing the first eight; more decompositions exist.
