Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131862, here are decompositions:

13 + 131849 = 131862
23 + 131839 = 131862
79 + 131783 = 131862
83 + 131779 = 131862
103 + 131759 = 131862
113 + 131749 = 131862
131 + 131731 = 131862
149 + 131713 = 131862

Showing the first eight; more decompositions exist.
