Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151836, here are decompositions:

19 + 151817 = 151836
23 + 151813 = 151836
37 + 151799 = 151836
53 + 151783 = 151836
67 + 151769 = 151836
103 + 151733 = 151836
107 + 151729 = 151836
149 + 151687 = 151836

Showing the first eight; more decompositions exist.
