Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11870, here are decompositions:

3 + 11867 = 11870
7 + 11863 = 11870
31 + 11839 = 11870
37 + 11833 = 11870
43 + 11827 = 11870
127 + 11743 = 11870
139 + 11731 = 11870
151 + 11719 = 11870

Showing the first eight; more decompositions exist.
