Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123356, here are decompositions:

67 + 123289 = 123356
97 + 123259 = 123356
127 + 123229 = 123356
139 + 123217 = 123356
229 + 123127 = 123356
307 + 123049 = 123356
349 + 123007 = 123356
487 + 122869 = 123356

Showing the first eight; more decompositions exist.
