Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105320, here are decompositions:

43 + 105277 = 105320
67 + 105253 = 105320
109 + 105211 = 105320
223 + 105097 = 105320
283 + 105037 = 105320
349 + 104971 = 105320
367 + 104953 = 105320
373 + 104947 = 105320

Showing the first eight; more decompositions exist.
