Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11812, here are decompositions:

5 + 11807 = 11812
11 + 11801 = 11812
23 + 11789 = 11812
29 + 11783 = 11812
113 + 11699 = 11812
131 + 11681 = 11812
179 + 11633 = 11812
191 + 11621 = 11812

Showing the first eight; more decompositions exist.
