Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103256, here are decompositions:

19 + 103237 = 103256
73 + 103183 = 103256
79 + 103177 = 103256
157 + 103099 = 103256
163 + 103093 = 103256
379 + 102877 = 103256
397 + 102859 = 103256
463 + 102793 = 103256

Showing the first eight; more decompositions exist.
