Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105282, here are decompositions:

5 + 105277 = 105282
13 + 105269 = 105282
19 + 105263 = 105282
29 + 105253 = 105282
31 + 105251 = 105282
43 + 105239 = 105282
53 + 105229 = 105282
71 + 105211 = 105282

Showing the first eight; more decompositions exist.
