Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130836, here are decompositions:

7 + 130829 = 130836
19 + 130817 = 130836
29 + 130807 = 130836
53 + 130783 = 130836
67 + 130769 = 130836
107 + 130729 = 130836
137 + 130699 = 130836
149 + 130687 = 130836

Showing the first eight; more decompositions exist.
