Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11810, here are decompositions:

3 + 11807 = 11810
31 + 11779 = 11810
67 + 11743 = 11810
79 + 11731 = 11810
109 + 11701 = 11810
193 + 11617 = 11810
223 + 11587 = 11810
283 + 11527 = 11810

Showing the first eight; more decompositions exist.
