Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105360, here are decompositions:

19 + 105341 = 105360
23 + 105337 = 105360
29 + 105331 = 105360
37 + 105323 = 105360
41 + 105319 = 105360
83 + 105277 = 105360
97 + 105263 = 105360
107 + 105253 = 105360

Showing the first eight; more decompositions exist.
