Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10156, here are decompositions:

5 + 10151 = 10156
17 + 10139 = 10156
23 + 10133 = 10156
53 + 10103 = 10156
89 + 10067 = 10156
149 + 10007 = 10156
227 + 9929 = 10156
233 + 9923 = 10156

Showing the first eight; more decompositions exist.
