Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11858, here are decompositions:

19 + 11839 = 11858
31 + 11827 = 11858
37 + 11821 = 11858
79 + 11779 = 11858
127 + 11731 = 11858
139 + 11719 = 11858
157 + 11701 = 11858
181 + 11677 = 11858

Showing the first eight; more decompositions exist.
