Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105446, here are decompositions:

67 + 105379 = 105446
73 + 105373 = 105446
79 + 105367 = 105446
109 + 105337 = 105446
127 + 105319 = 105446
193 + 105253 = 105446
349 + 105097 = 105446
409 + 105037 = 105446

Showing the first eight; more decompositions exist.
