Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10124, here are decompositions:

13 + 10111 = 10124
31 + 10093 = 10124
151 + 9973 = 10124
157 + 9967 = 10124
193 + 9931 = 10124
223 + 9901 = 10124
241 + 9883 = 10124
307 + 9817 = 10124

Showing the first eight; more decompositions exist.
