Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105404, here are decompositions:

3 + 105401 = 105404
7 + 105397 = 105404
31 + 105373 = 105404
37 + 105367 = 105404
43 + 105361 = 105404
67 + 105337 = 105404
73 + 105331 = 105404
127 + 105277 = 105404

Showing the first eight; more decompositions exist.
