Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151824, here are decompositions:

7 + 151817 = 151824
11 + 151813 = 151824
37 + 151787 = 151824
41 + 151783 = 151824
53 + 151771 = 151824
107 + 151717 = 151824
131 + 151693 = 151824
137 + 151687 = 151824

Showing the first eight; more decompositions exist.
