Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122456, here are decompositions:

3 + 122453 = 122456
7 + 122449 = 122456
13 + 122443 = 122456
67 + 122389 = 122456
109 + 122347 = 122456
157 + 122299 = 122456
193 + 122263 = 122456
283 + 122173 = 122456

Showing the first eight; more decompositions exist.
