Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10218, here are decompositions:

7 + 10211 = 10218
37 + 10181 = 10218
41 + 10177 = 10218
59 + 10159 = 10218
67 + 10151 = 10218
79 + 10139 = 10218
107 + 10111 = 10218
127 + 10091 = 10218

Showing the first eight; more decompositions exist.
